Table/tree table refresh issue

I create a table and tree table, we see the refresh happen when adding or deleting a row. We are trying to reach the following behavior:
1) when adding a row, it should add (before or after or END) and scroll to that location and put focus on that row. In a simple case where we do not have to scroll down to some page, this should present minimal refresh
2) Deleting a row or multiple rows, should present minimal refresh
3) we don't want to fetch at all for ADD and delete rows. Only in pagination scrolling we should fetch.
Does anyone have the similar requirement for the behavior of Table /Tree table?
how do you achieve that ?

Hi KRISHNA,
there is no other way as a complete page refresh with the normal APEX trees. But you could use an javascript library instead like JQuery or ExtJS.

Tree table is not reflecting the updated model data changes at the front end

I have two tables ,
1) Provider table(tree table) 2)member table
I have implemented drag and drop functionality using jQuery UI on both tables.
In my scenario when I drag a member from the member table and drop it on the Provider table and also when I delete an assigned member from the provider table I will update the data fetched from odata model and again I will call the method which binds the data to the provider table so that the table will reflect the changes.
here is the code,
on drop:
$("#Provider tbody tr").droppable({
drop: function(event){
oController.AssignMember(oProviderId, oMemberId)
}).disableSelection();
Assign member function: here am updating the model.
AssignMember : function(oProviderId, oMemberId){
var oModel = new sap.ui.model.odata.ODataModel("../../../services/provider.xsodata/", true);
var oParameters = {};
oParameters.PROVIDER_ID = oProviderId;
oParameters.MEMBER_ID = oMemberId;
oParameters.CREATED_ON = new Date();
oModel.setHeaders({"content-type" : "application/json;charset=utf-8"});
oModel.create( "/PROVIDERMEMBERS", oParameters, null, function() {
var oController = sap.ui.controller("adsm.provider.member_assignment_view");
oController.GetProviderData();
},function(jqXHR) {
var errorMessage = jqXHR.response.body;
var jsondata = JSON.parse(errorMessage);
sap.ui.commons.MessageBox.alert(jsondata.error.message.value);
GetProviderData function: here i bind the data to the table
GetProviderData: function(){
var oModel = new sap.ui.model.odata.ODataModel("../../../services/provider.xsodata/", true);
var Context = "/PROVIDERS?expand=ASSIGNEDMEMBERS&$select=NAME,ID,ASSIGNEDMEMBERS/NAME,ASSIGNEDMEMBERS/ID,ASSIGNEDMEMBERS/PROVIDER_ID";
var oTable = sap.ui.getCore().byId("tblProviders");
oModel.read(Context, null, null, true, onSuccess, onError);
function onSuccess(oEventdata){
var outputJson = {};
var p = 0;
var r = {};
if (oEventdata) {
r = oEventdata;
try {
if (oEventdata.d){
r = oEventdata.d;
} catch(e){
//alert('oEventdata.d failed');
try {
if (oEventdata.d.results){
r = oEventdata.d.results;
} catch(e){
//alert('oEventdata.d.results failed');
try {
if (oEventdata.results){
r = oEventdata.results;
} catch(e){
//alert('oEventdata.results failed');
$.each(r, function(i, j) {
outputJson[p] = {};
outputJson[p]["NAME"] = j.NAME;
outputJson[p]["ID"] = j.ID;
outputJson[p]["PROVIDER_ID"] = j.ID;
outputJson[p]["DELETE"] = 0;
var m = 0;
if (j.ASSIGNEDMEMBERS.results.length > 0) {
$.each(j.ASSIGNEDMEMBERS.results, function(a,b) {
outputJson[p][m] = { NAME: b.NAME,
ID : b.ID,
PROVIDER_ID: b.PROVIDER_ID,
DELETE: 1};
m++;
p++;
var oModel = new sap.ui.model.json.JSONModel();
oModel.setData(outputJson);
oTable.setModel(oModel);
function onError(oEvent){
console.log("Error on Provider Members");
oTable.bindRows({
path:"/"
Its working fine in chrome but in IE the model data gets updated but the table is not reflecting the changes at front end.Can anyone suggest me a possible solution to fix this?
Please have a look at the attached screen shots.

Tree Table is not getting refreshed properly in Jdev 11.1.2.0

Hi,
I am seeing a peculiar issue with tree table not getting refreshed in Jdev 11.1.2.0.
Let me explain you my use case.
I have a tree table in a page, where the first column is displayed as selectBooleanRadio component. When user selects this selectBooleanRadio component, that treetable node should get expanded and at the same time all the child records(I have a select boolean check box component(transient attribute) at the child level) for that node should get selected. This is to allow user to unselect the child records, which he/she does not want to process further(some functionality).
Now when the user selects any radio button, the tree table node is not expanded, but the arrow beside the radio button for that node can be seen as expanded.
I thought it may be a partial trigger issue, so i tried refreshing the tree table programatically as well. But it was of no use.
Then I set the partial triggers wrt to SelectBooleanRadio component on the parent container of the TreeTable. After which somehow the node got expanded but the tree table shrinks in width and the actual disclosure functionality of a tree table is lost.
The same use case works perfectly fine in Jdev 11.1.1.5.
For reference:
I created a sample test case(Dept/Emp) in jdev version 11.1.1.5, which works fine. Workspace: http://adf-use-cases.googlecode.com/files/TreeTable1.rar
But the same test case, when i created in jdev version 11.1.2.0, gives issues. Workspace: http://adf-use-cases.googlecode.com/files/TreeTableUseCase.rar
If you download the application and run in respective jdev version, you will get to know more about the issue.
Please let me know, If I am doing anything wrong in the implementation of this use case.
Any help/suggestions are appreciated.
Thanks
Umesh
Note: My complete application is in Jdev 11.1.2.0, so I can't degrade my jdev version to 11.1.1.5.

Thanks Frank for the reply.
But upgrading the jdeveloper to 11.1.2.2 is not an ideal solution for us now, because of the size of the project.
Some how, the issue of refreshing the tree table is resolved. I am using a command button with clientComponent to true and causing a full page refresh.
I am not sure, if this is a perfect solution.
As you said, that this behavior may be an issue with the Jdev version 11.1.2.0, I am using. I am going with the above said approach.

ADF Issue with Tree Table , Child Row not getting rendered.

Hi All,
I am trying to show a single Level Master-Detail Table via ADF Tree Table.
I have MasterVO : InventoryVO (1 SubInventoryCode)
DetailVO: SubInventoryVO (n :SubInventoryCode)
Both VOs are SQL query based VO with bindVariables.
I have a viewLink between MasterVO and ChildVO (1:n relationship)
I dragged and drop the MasterVO as a tree Table. I added the Rule in the Tree Binding too.
I have the Tree table under a Tab , I execute the AM impl method when the Tab is clicked where I set the bindvariables of the MasterVO and ChildVO and execute it.
when I run the Page , the VO query gets executed but the I am able to see only the MasterVO Datas, and when I click MasterVO ROW , the Table doesnt expand and it doesnt render any ChildVO ROws.

I was able to find the issue which is causing the problem, both the VOs are SQL Query Based VOs.
The ChildVO (SubInventoryVO) is has a bindvariable in its Query, which is losing its value when the viewlink accessor query gets appended to it.
Please find the query below
SELECT * FROM (SELECT MOTV.ORGANIZATION_CODE, MOTV.SUBINVENTORY_CODE
FROM MTL_ONHAND_TOTAL_V MOTV
WHERE INVENTORY_ITEM_ID = :P_INVENTORY_ITEM_ID) QRSLT WHERE ORGANIZATION_CODE = :Bind_OrganizationCode Though I am setting the VO query before the Table is rendered, ":P_INVENTORY_ITEM_ID".
Its Losing its value, when the above whereclause "ORGANIZATION_CODE = :Bind_OrganizationCode " gets appended to it.
I am thinking to use ExecuteWithParams Operation on SelectionListener method of the Tree Table to set the ":P_INVENTORY_ITEM_ID" bind variable, but I also want the viewLinkAccessor rule also to be applied ..
Please suggest me how to retain the implicit bindVariable of the Query.

Issue with ADF Tree Table

Hi,
I have the following requirement where i need to display a tree table. Here is how the initial implementation is:
I have created the read only view for : ManagersVO > PoolsVO > MachinesVO. Where 'MachinesVO' is the destination view. And created view links between ManagersVO & PoolsVO using ManagerId and PoolsVO & MachinesVO using PoolId.
And using this implementation, successfully created tree table on the UI. Now we got an enhancement for this:
i.e., MachinesVO should return list of machines as per user logs in. i.e., we have 4 different roles. 'Super Admin', 'Sys Admin', 'App Admin', 'End User'. The default query for MachinesVO is for 'Super Admin'. The query for other user roles is different except the SELECT statement.
The requirement is to dynamically change the query of MachinesVO based on user logs in and display the tree table accordingly. To implement the same i have tried using setQuery() operation on 'MachinesVO' which results with the following error:
JBO-26016: InvalidOperException
Cause: You cannot set customer query (calling setQuery()) on a view object if it is the detail view object in a master detail view link.
Action: Do not call setQuery() if the view object is a detail.
Can one suggest me a best solution to implement this.
Thanks & Regards,
Kiran

Hi Navaneetha Krishnan,
Here is how i implemented based on your comments. As i have tree table based 3 different VO's, created the following method at middle view(i.e., PoolsVO).
1.Tree Model hierarchy
ManagersVO > PoolsVO > MachinesVO
I actually want to filter the data at Machines level. Hence wrote a method at PoolsVOImpls and exposed it in the PoolsVO client interface. Here is the code that i have placed in the PoolVOImpl
public class PoolsVOImpl extends ViewObjectImpl implements PoolsVO{
     * This is the default constructor (do not remove).
    public PoolsVOImpl () {
public void filterMachinesDataByUserRole(String userRole,String vzId){
    Row row = getCurrentRow();
    String query = "";
    if(row != null){
      RowSet rowSet = (RowSet)row.getAttribute("MachinesVO");
      if(rowSet != null){
        MachinesVOImpl machinesVOImpl = (MachinesVOImpl)rowSet.getViewObject();
        if(userRole.equalsIgnoreCase("SYS ADMIN")){
                machinesVOImpl .setWhereClause(query related to sysadmin);
         //Similarly for other user roles.
         executeQuery();
}And this piece of code needs to be executed before the jsff(which has the tree table) renders. Hence, i created a this methodAction as a default activity in the respective taskflow where the jsff is placed. Once this method get executed, the page should render the machines specific to the user.
Here is the issue: getCurrentRow() method call is returning always NULL.
Please correct me if i'm doing something wrong. I do tried the above mentioned approach by creating the method at '*ManagersVOImpl*' level too. Still the same issue.
Thanks & Regards,
Kiran

Scrollbar refresh issue in ADF Table

Hello, All
We have an issue regarding the ADF Tables. Please let me know if it is a Oracle bug. All of us know that 'ExecuteQuery' operation refreshes the cache in View Objects.
But, based on our testing results, there might be a table refresh issue on vertical scrollbars after this opertion is executed.
Settings:
In the attached example project, we have a ADF RichTable included in a PanelCollection.
In addition, We set 'AutoHeightRows' property on this ADF RichTable in order to show scrollbars on the PanelCollection.
Furthremore, a standard CommandButton is created on the toolbar to execute queries.
Experimental Steps:
1. Use your mouse to move the vertical scrollbar to around the center of its range. This behavior causes the scrollbar scrolling vertically.
2. Click on any row showing in the table right now, make it to be the active row.
3. Press the 'ExecuteQuery' button, waiting for the table refresh.
Results:
1. Active row moves to the first row in the rowset.
2. Vertical scrollbar stay in the center of its range without moving to the first row.
3. The first row is hidden from end users. The user can not see the active row in this case.
FYI:
The attached project can be accessed from the following link:
http://www.4shared.com/zip/Xn4Ki0DP/Application3.html
In this project, we tried to set 'partialTriggers' on RichTable and its surrounding PanelCollection separately. But, the refreshing issue still exists.

David He

Welcome David to forums.
Always mention your exact Jdev version. For more information read this: https://forums.oracle.com/forums/ann.jspa?annID=56
I too faced the similar kind of issue in one of my application.
As you have not mentioned the exact jdev version, I will tell you what I did in my application which was developed using Jdev 11.1.2.0
After the VO is executed, you can write the below line of code to show the first rows in the table.
applicationsRichTable.setDisplayRow(applicationsRichTable.DISPLAY_ROW_FIRST);
//applicationRichTable is the binding for the RichTable in managed beanHope it helps.

Problem with refresh issue in Table Overflow Area for LOV in edit mode

Hi Friends,
I am facing a problem with LOV if i keep this in Table Overflow area,
When i select a Employee name from the List of Value clicking on select button it will not refresh the lov to display the currently selected Employee Name, but if i click on show and hide link of Table overflow the selected employee name will be displayed.
But the if move the same lov item from Table Overflow area to Table layout it works fine.
I tried my best to look into this but i could not, can any one suggest me what i need to do for this refresh issue.
Regards,
Rahul

Hello Rahul,
Strange, it's working for me.
I assume you added Employees as reference entity to your updatable entity in your ViewObject.
Did you uncheck "Key attribute" in EmployeeId of your reference entity?
Anything in the log?

Issues while Populating data in Tree Table..

Hi,
I am using Tree Table component to populate Hierarchical data in it.
I create data controls based on web service proxy.
While creating Tree table i selected the Display Attributes to show in Tree table.
Now i am struck with two requirements:
1. At run time when i see the data in Tree table i can see that Display Attributes for mixed.
For Example:
Andrew> Phone
Work 123456789 // Here we can notice that, two attributes data displayed with on space gap. Phone Type and Phone number
Home 987654321 need to show some separation character between thenm something like : Work - 123456789 Is it possible?
> Email
work [email protected]
2. I need to show popup on click on Root node of the Tree table. If we take the above example, i want to perform a click event on "Andrew" so that i can popup and show some details.
But when i try to insert a command link in Node. Parent & Child nodes are populated with command link. How to have command link only for parent Node.
Code i am using:
*<af:treeTable value="#{bindings.contact.treeModel}" var="node"*
*selectionListener="#{bindings.contact.treeModel.makeCurrent}"*
*rowSelection="single"*
*binding="#{backingBeanScope.EditValidationDetails.tt1}"*
*id="tt1" width="920">*
*<f:facet name="nodeStamp">*
*<af:column id="c1" width="800" filterable="true">*
*<af:commandLink text="#{node}" id="cl2"/>*

GetSelectedRowKeys() returns more than one on Single Selection Tree Table

Hi,
I found that this issue occurring after PS3 (I think.)
I have a tree table component, which allows single row selection. There is a listener on a column of the tree table as follows:
public void listenPackageUnit(ValueChangeEvent valueChangeEvent)
Object oldKey = getTreeComponent().getRowKey();
try
* Retrieve index of selected package unit
* NOTE: Subtract 1 to remove no selection value. This only
* needs to be done if attached LOV has No Selection option set.
if (valueChangeEvent.getNewValue() != null)
Row row = null;
String selectedPackageUnit = null;
int packageUnitIndex = (Integer) valueChangeEvent.getNewValue();
packageUnitIndex--;
* Due to the no selection item, we need to prevent search of regular
* iterator if index is < 0. In this case we know the user selected
* the no selection (blank) value.
if (packageUnitIndex >= 0)
* Using index, determine the value of the selected package unit
DCIteratorBinding packageUnitsIterator =
(DCIteratorBinding) PasUiADFUtil.resolveExpression("#{bindings.PackageUnitsIterator}");
Row newRow =
packageUnitsIterator.getRowAtRangeIndex(packageUnitIndex);
selectedPackageUnit = (String) newRow.getAttribute("LookupCode");
RowKeySet selection = this.getTreeComponent().getSelectedRowKeys();
if (selection != null && selection.getSize() > 0)
for (Object facesTreeRowKey: selection)
this.getTreeComponent().setRowKey(facesTreeRowKey);
JUCtrlHierNodeBinding rowData =
(JUCtrlHierNodeBinding) this.getTreeComponent().getRowData();
row = rowData.getRow();
setSelectedLabel((String) row.getAttribute("Label"));
setSelectedLabelType((String) row.getAttribute("LabelType"));
row.setAttribute("PackageUnit", selectedPackageUnit);
getTreeComponent().setRowKey(oldKey);
finally
getTreeComponent().setRowKey(oldKey);
The issue is that getSelectedRowKeys() returns more than one when the user selects a child row in the tree table.
It seems to be returning the total number counting from the top parent through the child.
(For example, if the child is the second generation, it returns 2, and if the third generation, it returns 3.)
This is causing the issue that the method tries to update the attribute of the parent row with a value for the child row. (And it fails, because the attribute is updateable only while new.)
I remember getSelectedRowKeys() always returned one, the selected child itself, when I coded this around October, 2010.
Is this a design change after PS3? Why does it return more than one though the tree table is for single selection?
How can I get around this issue?
It would be truly appreciated if we can get any quick help, since we are at final testing phase of our product.
Thank you,
Tomo

Hi Vinod,
I found the solution. Thank you very much for your suggestions. :)
Now my listenSelection (custom listener of the tree table) looks like below:
public void listenSelection(SelectionEvent selectionEvent)
Row currentRow;
PasUiADFUtil.invokeEL("#{bindings.TransactionLabelTopLevelVO1.collectionModel.makeCurrent}",
new Class[] { SelectionEvent.class },
new Object[] { selectionEvent });
Object oldKey = getTreeComponent().getRowKey();
try
if (this.getTreeComponent() != null)
RowKeySet rks = this.getTreeComponent().getSelectedRowKeys();
Iterator keys = rks.iterator();
while (keys.hasNext())
List key = (List) keys.next();
this.getTreeComponent().setRowKey(key);
JUCtrlHierNodeBinding node =
(JUCtrlHierNodeBinding) this.getTreeComponent().getRowData();
if (node != null)
currentRow = node.getRow();
if (currentRow != null)
this.setSelectedRow(currentRow);
setSelectedLabel((String) currentRow.getAttribute("Label"));
setSelectedLabelType((String) currentRow.getAttribute("LabelType"));
String shippedItemFlag =
(String) currentRow.getAttribute("ShippedItemFlagValue");
if (shippedItemFlag != null && shippedItemFlag.equals("1"))
setDisableAdd(true);
else
setDisableAdd(false);
finally
getTreeComponent().setRowKey(oldKey);
/* Refresh Action menu and buttons */
RequestContext.getCurrentInstance().addPartialTarget(this.getActionMenu());
RequestContext.getCurrentInstance().addPartialTarget(this.getToolbar());
And my tree table is like below:
<af:treeTable value="#{bindings.TransactionLabelTopLevelVO1.treeModel}"
var="node" rowSelection="single" id="tt1"
contentDelivery="immediate" fetchSize="25"
emptyText="#{bindings.TransactionLabelTopLevelVO1.viewable ? commonFoundationMsgBundle.NO_DATA_TO_DISPLAY : commonFoundationMsgBundle.ACCESS_DENIED}"
selectionListener="#{pageFlowScope.MaintainTransactionSerialAssociationBean.listenSelection}"
binding="#{pageFlowScope.MaintainTransactionSerialAssociationBean.treeComponent}"
summary="#{maintainAssociationUiBundle.CONTAINER_SERIAL_HIERARCHY}">

Row Selection for second and subsequent level nodes in tree table

Hi All,
We have a .jsff page with tree bindings to display a three-level hierarchy tree table.Suppose the hierarchy is
-> Department
->-> Employees
->->-> Employee details.
I have a use case where-in when we add the employee node within a department,the department node must expand and the newly added employee node must be selected.
In both the cases(for new department or employee), we are following the approach mentioned below:
1. Get the treeTable Iterator.
2.Adding the new object to the java ArrayList which is bound to the corresponding level in the tree.
3.Refreshing the treeTable iterator.
4.Execute treeTable.setSelectedRowKeys()
5.Add a partial target to the treetable.
The issue is that the new employee gets added but the upper-level department node collapses and no selection is performed on the new employee node.
But when we add a new department node, it gets selected on creation.
Is there any additional steps to be performed for second-level row selection?

Hi,
Thanks for the reply.
I looked at the code given in sample 61.
In the sample, a new node is not added dynamically (for ex.either new location or its child nodes.)
As mentioned in the above post, after adding a new node at a level in our use case, when we perform the refresh of the tree-table's iterator,the selection state of the rows is not shown on the table.
If the tree-table's iterator is not refreshed and the treeTable.setSelectedRowKeys() is executed, the rows get selected but the subsequent node additions do not show up in the table as the table's iterator is not refreshed.
Any sample code is available where in both the addition of new node and its selection is performed at the same time?
Thanks.

DETACHED MODE ON TREE TABLE

Hi,
I have an issue with detached mode on Tree table. In one of the page, I'm having a Tree table in Panel Collection with "Detach" enabled. In Tree Table, I have a column "Actions" and it has links for every record. Using these links, user performs operations like 'allocate' and 'de-allocate '.
I allocated a resource to the Tree table, now the "Deallocate" operation is allowed on that particular row of Tree table.
Now I click the "Detach" button, Tree table is displayed in Detached Mode. When I click the "De-allocate" link of Tree table, allocated resource is deallocated without issue, but the Tree table no more stays in Detached mode.
Here whenever user allocates / deallocates resource from Tree table, I refresh the tree table. I use the binding attribute to refresh the Tree table component.
Can I restrict the Tree table to stay in Detached mode, even after refreshing the component?
Please let me know if there is any solution.
Thanks
Ravi

Hi,
do your links perform a page refresh ? Make sure the links have their partialSubmit property set to true as otherwise they perform a full page refresh.

The detail part of table doesn't refresh after deleting a row

Hello!
I'm developing a Master-Detail table with some a functionality. Particularly, I want to invoke a DELETE function in the Detail part of the table.
For this purpose, I placed a Command button to the tableSelectOne component of the Detail part of the table, which stores current row key and calls another page. On this (<another>) page I created a ReadOnly form with data related to the row of Detail table, which key is stored. In addition, I added there two Command buttons. First of them is a CancelButton, which does nothing except returning to master-detail page. The second is a DeleteButton, which executes a RemoveEntity method and returns to master-detail page, too.
When I'm tried to delete in this way a row from detail part of table, I discovered, that this row is really deleted from the database, but it doesn't affect on the content of the Detail part of the table. Any kinds of refreshing couldn't aid me, only restart of the application.
Could anybody help me to solve this problem?
Thank in advance.

Hi,
I'm facing the same problem but Frank's solution doesn't fix it.
you need to define an invoke action in the binding
for your m/d page and set it into the page binding's
execute section. Then set the condition for invoking
the action to !postback. This will re-execute the
iteratorThis efectively re-executes the iterator, so the master table data is refreshed. You can see the TopLink log showing the query to the db (I'm using TopLink instead of BC). The problem is that the detail rows are queried only once and only the inserts and updates are displayed, not the deletes.
I think the problem may be related to PPR or some cache issue.
See the BC tutorial
http://www.oracle.com/technology/obe/ADFBC_tutorial_10
13/ADFBC_tutorial.pdf
See page 86 "Adding the ServiceHistories Data". This
defines a invoke action for this kinf of task. More
example code is contained in the SRDemo sampleThe tutorial doesn't contain a scenario with master-detail deleting detail records (neither the BC tutorial, nor the TopLink one) so it can't help me :(
The only solution I can think of is using a different model method (a method in the SessionFacade for TopLink) for the detail table (one that takes the master PK as parameter and retrieves the corresponding detail records) and have a selectionListener in the selection component of the master re-execute the method (passing the PK from the master table current row).
Is there a solution that doesn't require the use of a separate method for the detail?
Thanks,
Miguel

Cannot sort child rows in multilevel tree table

Hi,
I originally hijacked a two-year-old forum thread that was vaguely similar to my issue, but a kind forum moderator split my post away
(and deleted my other hijack post asking this same question)
so that my inquiry might be viewable on its own.
Hopefully someone can pay attention to my issue instead of getting it confused with those other old forum threads.
So, here we go ...
Is sorting in a treeTable at a particular level possible? Just want to let you I have tried the following approaches to do this. But it dis not work for me.
I have tree table with 2 levels. I am trying to sort the child rows based on its column say "Display Sequence".
User can type in number in this column which contains input text. On value change event of the this field, all the
child rows in the level 2 need to be sorted. This needs to be done without committing the data. On commit it works,
because it sorts based on order by clause. I want the child rows to be sorted on value change event. Following
various approaches I tried.
TreeModel tModel = (TreeModel)treeTable.getValue();
SortCriterion sortCriterion = new SortCriterion("DisplaySequence",true);
List<SortCriterion> sortCriteriaList = new ArrayList<SortCriterion>();
sortCriteriaList.add(sortCriterion);
tModel.setSortCriteria(sortCriteriaList);
The above code does not work, As "DisplaySequence" is not available in the parent view object.
Here is approach no 2
JUCtrlHierBinding treeTableBinding = null;
JUCtrlHierNodeBinding nodeBinding = null;
JUCtrlHierNodeBinding parentNodeBinding = null;
JUCtrlHierTypeBinding nodeHierTypeBinding = null;
Key rowKey;
Object dispSeqObj;
Number displaySequence = null;
Map<Key,Number> keyValueMap = null;
Set<Key> emptyValueKeySet = null;
Map<Key,Number> sortedKeyValueMap = null;
DCIteratorBinding target = null;
Iterator iter = null;
int rowIndex = 1;
RowSetIterator rsi = null;
Row currentRow = null;
Row row = null;
RowKeySet selectedRowKey = lookupTreeTable.getSelectedRowKeys();
Iterator rksIterator = selectedRowKey.iterator();
if (rksIterator.hasNext()) {
List key = (List)rksIterator.next();
System.out.println("key :"+key);
treeTableBinding = (JUCtrlHierBinding) ((CollectionModel)lookupTreeTable.getValue()).getWrappedData();
nodeBinding = treeTableBinding.findNodeByKeyPath(key);
parentNodeBinding = nodeBinding.getParent();
//rsi = nodeBinding.getParentRowSetIterator();
rsi = parentNodeBinding.getChildIteratorBinding().getRowSetIterator();
keyValueMap = new LinkedHashMap<Key,Number>();
emptyValueKeySet = new LinkedHashSet<Key>();
// Gets the DisplaySequence by iterating through the child rows
while(rsi.hasNext()) {
if(rowIndex==1)
row = rsi.first();
else
row = rsi.next();
rowKey = row.getKey();
dispSeqObj = row.getAttribute("DisplaySequence");
if(dispSeqObj!=null && dispSeqObj instanceof Number) {
displaySequence = (Number)dispSeqObj;
keyValueMap.put(rowKey, displaySequence);
}else {
emptyValueKeySet.add(rowKey);
rowIndex++;
rowIndex = 0;
// Sort the numbers using comparator
DisplaySequenceComparator dispSeqComparator = new DisplaySequenceComparator(keyValueMap);
sortedKeyValueMap = new TreeMap<Key,Number>(dispSeqComparator);
sortedKeyValueMap.putAll(keyValueMap);
rsi.reset();
nodeHierTypeBinding = nodeBinding.getHierTypeBinding();
System.out.println("nodeHierTypeBinding :"+nodeHierTypeBinding);
String expr = nodeHierTypeBinding.getTargetIterator();
if (expr != null) {
Object val = nodeBinding.getBindingContainer().evaluateParameter(expr, false);
if (val instanceof DCIteratorBinding) {
target = ((DCIteratorBinding)val);
ViewObject targetVo = target.getViewObject();
System.out.println("targetVo :"+targetVo);
targetVo.setAssociationConsistent(true);
//ri = target.findRowsByKeyValues(new Key[]{rowData.getRowKey()});
rsi = parentNodeBinding.getChildIteratorBinding().getRowSetIterator();
//rsi = nodeBinding.getParentRowSetIterator();
// Rearrange the tree rows by inserting at respective index based on sorting.
ViewObject vo = nodeBinding.getViewObject();
iter = sortedKeyValueMap.keySet().iterator();
while(iter.hasNext()) {
currentRow = rsi.getRow((Key)iter.next());
rsi.setCurrentRow(currentRow);
rsi.setCurrentRowAtRangeIndex(rowIndex);
//rsi.insertRowAtRangeIndex(rowIndex, currentRow);
rowIndex++;
iter = emptyValueKeySet.iterator();
while(iter.hasNext()) {
currentRow = rsi.getRow((Key)iter.next());
rsi.setCurrentRow(currentRow);
rsi.setCurrentRowAtRangeIndex(rowIndex);
//rsi.insertRowAtRangeIndex(rowIndex, currentRow);
rowIndex++;
rsi.closeRowSetIterator();
AdfFacesContext.getCurrentInstance().addPartialTarget(treeTable);
private class DisplaySequenceComparator implements Comparator {
Map<Key,oracle.jbo.domain.Number> dispSeqMap = null;
public DisplaySequenceComparator(Map<Key,oracle.jbo.domain.Number> dispSeqMap) {
this.dispSeqMap = dispSeqMap;
public int compare(Object a, Object b) {
Key key1 = (Key)a;
Key key2 = (Key)b;
oracle.jbo.domain.Number value1 = dispSeqMap.get(key1);
oracle.jbo.domain.Number value2 = dispSeqMap.get(key2);
if(value1.getValue() > value2.getValue()) {
return 1;
} else if(value1.getValue() == value2.getValue()) {
return 0;
} else {
return -1;
In the above code I tried to perform sorting of DisplaySequence values using comparator, then tried to rearrange
nodes or rows based on sort resurts. But rsi.insertRowAtRangeIndex(rowIndex, currentRow) give
DeadViewException...unable to find view reference. While setting current row also does not work.
Approach 3.
DCIteratorBinding iter1 =
bindings.findIteratorBinding("childIterator");
iter1.executeQuery();
SortCriteria sc = new SortCriteriaImpl("DisplaySequence",false);
SortCriteria [] scArray = new SortCriteria[1];
scArray[0] = sc;
iter1.applySortCriteria(scArray);
Any help in Sorting Child nodes ADF treeTable is appreciated. Thanks in Advance.

Hi Frank,
Thanks for your reply. I have tried similar approach for sorting tree table child rows based on user specified number and it works. But there is a limitation for this. This sorting works only for read only/transient view object. For updatable view object after sorting, data cannot be saved or updated, as it cannot find the rowid. Here is what I tried
In the ParentViewImpl class,
1. overrode the method createViewLinkAccessorRS, so that this method is forcefully executed.
@Override
protected ViewRowSetImpl createViewLinkAccessorRS(AssociationDefImpl associationDefImpl,
oracle.jbo.server.ViewObjectImpl viewObjectImpl,
Row row,
Object[] object) {
ViewRowSetImpl viewRowSetImpl = super.createViewLinkAccessorRS(associationDefImpl, viewObjectImpl, row, object);
return viewRowSetImpl;
2. Added the following method, which will be invoked on valueChange of DisplaySequence in child row. Expose this method through client interface. This method accept a parameter i.e. parent row key of the child row.
public void sortChildRecords(Key parentKey) {
ViewObject viewObject = null;
String type = null;
if(parentKey==null) {
Row [] row = this.findByKey(parentKey, 1);
RowSet rowSet = (RowSet)row[0].getAttribute("ChildVO");
viewObject = rowSet.getViewObject();
viewObject.setSortBy("DisplaySequence asc");
}else {
Row row = getCurrentRow();
RowSet rowSet = (RowSet)row.getAttribute("ChildVO");
viewObject = rowSet.getViewObject();
viewObject.setSortBy("DisplaySequence asc");
this.setQueryMode(ViewObject.QUERY_MODE_SCAN_DATABASE_TABLES |
ViewObject.QUERY_MODE_SCAN_ENTITY_ROWS);
this.executeQuery();
For custom sort, lets say all the numbers should be display first in ascending order, and null or empty values to be display at the end need to override the getRowComparator method in the ChildViewImpl class,
Here is the code for the same
@Override
public Comparator getRowComparator() {
SortCriteria sortCriteria = new SortCriteriaImpl("DisplaySequence",false);
SortCriteria [] sortCriterias = new SortCriteria[1];
sortCriterias[0] = sortCriteria;
return new DisplaySequenceComparator(sortCriterias);
private class DisplaySequenceComparator extends RowComparator {
public DisplaySequenceComparator(SortCriteria [] sortCriterias) {
super(sortCriterias);
public int compareRows(Row row1, Row row2) {
Object dispSeqObj1;
Object dispSeqObj2;
Number dispSeq1 = null;
Number dispSeq2 = null;
boolean compareRow1 = true;
boolean compareRow2 = true;
if(row1!=null) {
dispSeqObj1 = row1.getAttribute("DisplaySequence");
if(dispSeqObj1!=null && dispSeqObj1 instanceof Number) {
dispSeq1 = (Number)dispSeqObj1;
}else {
compareRow1 = false;
if(row2!=null) {
dispSeqObj2 = row2.getAttribute("DisplaySequence");
if(dispSeqObj2!=null && dispSeqObj2 instanceof Number) {
dispSeq2 = (Number)dispSeqObj2;
}else {
compareRow2 = false;
if(compareRow1 && compareRow2) {
if(dispSeq1.getValue() > dispSeq2.getValue()) {
return 1;
} else if(dispSeq1.getValue() == dispSeq2.getValue()) {
return 0;
} else {
return -1;
if(!compareRow1 && compareRow2)
return 1;
if(compareRow1 && !compareRow2)
return -1;
return 0;
The above solution works properly, and sorts the child tree rows. But while saving the changes, update fails. I also came to know that in-memory sorting is applicable to read-only/transient view objects from some blogs and also mentiond in this link http://docs.oracle.com/cd/E24382_01/web.1112/e16182/bcadvvo.htm
Is there any way that updatable view objects can be sorted and saved as well?
Thanks,
Abhishek

How to use tree tables with CRUD operation for begineers ADF 11g

This is Friday night call for help.
This is only few sample ressources on the web for tree table and only one with CRUD operation.
I used this one http://jobinesh.blogspot.com/2010/05/crud-operations-on-tree-table.html because this is the only one that address CRUD.
And it is shaky. Deletion works fine but insertion not very well. This is working using custom code provided below.
Depending if the user selection in the tree, the code insert from the master node to the children node.
Any other options because it is not working well.
Also where Oracle describes how to use the row, rowset, itorator API? This is really hard to understand like almost if we should not use it.
then if not how can I insert in tree with two nodes and insert in the parent or children depending the users selection.
Lately I 'been posting questions on this forum with no response. This hurts. I understand developers cannot spend their time on this but People from Oracle, please help. We pay licenses...
public void createChildren(RowIterator ri, Key selectedNodeKey) {
final String deptViewDefName = "model.DepartmentsView";
final String empViewDefName = "model.EmployeesView";
if (ri != null && selectedNodeKey != null) {
Row last = ri.last();
Key lastRowKey = last.getKey();
// if the select row is not the last row in the row iterator...
Row[] found = ri.findByKey(selectedNodeKey, 1);
if (found != null && found.length == 1) {
Row foundRow = found[0];
String nodeDefname =
foundRow.getStructureDef().getDefFullName();
if (nodeDefname.equals(deptViewDefName)) {
RowSet parents =
(RowSet)foundRow.getAttribute("EmployeesView");
Row childrow = parents.createRow();
parents.insertRow(childrow);
} else {
RowSet parents =
(RowSet)foundRow.getAttribute("EmployeesView");
Row childrow = parents.createRow();
childrow.setAttribute("DepartmentId",
foundRow.getAttribute("DepartmentId"));
parents.insertRow(childrow);
} else {
System.out.println("Node not Found for " + selectedNodeKey);
}

I am looking for a sample that describe how to design a jsf page with a tree table.
So you have Department and employees. In the tree first comes Department and if you click the node you see the employees assigned to this department.
I need to be able to insert a new department or a new employee from the tree table by clicking on a insert button in the panel collection toolbar depending on user selection in the tree.
I got part of it working but not good enough.
By problem is the get insertion working
I have a createChildren method in my AM implementation that get in input a RowIterator and selected node key.
To goal is to create new records depending of the user selection and the input parameters get populated by the binding like this:
#{backing_treeSampleBean.selectedNodeRowIterator} #{backing_TreeSampleBean.selectedNodeRowkey} via method binding with parameters.
Is it the right approach?
First to be able to insert a parent record, I select nothing in the tree and ri and selectedNodeKey comes to null
we run this code
ViewObjectImpl vo = getSchHolidaySchedExceptionsView1();
//ViewObjectImpl vo = getDepartmentsView1();
Row foundRow = vo.first();
Row childrow = vo.createRow();
vo.insertRow(childrow);
A new blank entry appears in the parent node and we enter a value.
The the problem starts when we want to add a child to this parent.
We select the created parent and press the insert button, this code get executed
if (nodeDefname.equals(deptViewDefName))
//list of the children of the parent and create an new row
RowSet childRows = (RowSet)foundRow.getAttribute("SchHolidayExceptionDatesView");
Row childrow = childRows.createRow();
childRows.insertRow(childrow);
But the new entry does not appear, it is almost like it would be created for a different parent because this is a mandatory field that is not feel in yet and the interface complaints of a missing value. It is created somewhere just not a the right place... This is my guess.
Do you see something wrong with the code?
The full code og my create children method is there below
I am using jdeveloper 11.1.1.3.0 any issues with tree table to know about with this version?
Thanks for your help
public void createChildren(RowIterator ri, Key selectedNodeKey) {
final String deptViewDefName = "com.bcferries.app.pdfroutesched.model.SchHolidaySchedExceptionsView";
final String empViewDefName = "com.bcferries.app.pdfroutesched.model.SchHolidayExceptionDatesView";
if (ri != null && selectedNodeKey != null) {
// last row
Row last = ri.last();
Key lastRowKey = last.getKey();
// if the select row is not the last row in the row iterator...
Row[] found = ri.findByKey(selectedNodeKey, 1);
if (found != null && found.length == 1) {
// foundRow is the row selected
Row foundRow = found[0];
// The row selected can be the parent node or the child node
String nodeDefname = foundRow.getStructureDef().getDefFullName();
// if parent row
if (nodeDefname.equals(deptViewDefName))
//list of the children of the parent and create an new row
//works but we try to resolve the creation of a parent
RowSet childRows = (RowSet)foundRow.getAttribute("SchHolidayExceptionDatesView");
Row childrow = childRows.createRow();
//childrow.setAttribute("HolidayDate", new java.util.Date().getDate());
System.out.println("insert child row from master");
childRows.insertRow(childrow);
} else
//RowSet ParentRow = (RowSet)foundRow.getAttribute("SchHolidaySchedExceptionsView");
//RowSet childRows = (RowSet)ParentRow.first().getAttribute("SchHolidayExceptionDatesView");
Row childrow = ri.createRow();
System.out.println("insert child row from child ");
} else {
System.out.println("Node not Found for " + selectedNodeKey);
} else {
System.out.println(" param null try creating for first row : " +
ri + " * " + selectedNodeKey);
ViewObjectImpl vo = getSchHolidaySchedExceptionsView1();
Row foundRow = vo.first();
Row childrow = vo.createRow();
vo.insertRow(childrow);
}

Deleting the Row from the table is not refreshing the contents in the form

Hi,
We developed a table and form in the same UI based on the following suggestion.
Display and edit currently selected row of ADF Table in ADF Form
1. Created one view object based on the employees table.
2. dragged the view object to the UI as table.
3. dragged the view object as form.
4. set partial triggers on the form's container (panelformlayout) as tableId.
Tested the application with the edit options and everything is working fine. But the problem comes when we delete the record from table. it is not refreshing the form based on the newly selected row after deleting the record. If we commit the data the form contents are updated to the selected row (which is not desired).
Can you please suggest how to fix the issue, refreshing the form with the selected row after deleting the records.
Thanks and Regards,
S R Prasad

The Code snippet looks fine. I think, the issue is in the partial trigger setting
4. set partial triggers on the form's container (panelformlayout) as tableId.In order to the table to get refreshed, the table's partialTriggers property should be set to id of the delete Button.
Go to table, select partialTriggers in the Property Inspector, Click on Expression Builder at the right and select the delete Button.
Can you set this and check?
Sample Code:
<af:panelHeader text="panelHeader 1" id="ph1">
<f:facet name="context"/>
<f:facet name="menuBar"/>
<f:facet name="toolbar">
<af:commandButton text="Delete" id="cb1"/>
</f:facet>
<f:facet name="legend"/>
<f:facet name="info">
<af:table var="row" rowBandingInterval="0" id="t1"
partialTriggers="::cb1">
<af:column sortable="false" headerText="col1" id="c1">
<af:outputText value="#{row.col1}" id="ot1"/>
</af:column>
<af:column sortable="false" headerText="col2" id="c4">
<af:outputText value="#{row.col2}" id="ot3"/>
</af:column>
<af:column sortable="false" headerText="col3" id="c3">
<af:outputText value="#{row.col3}" id="ot4"/>
</af:column>
<af:column sortable="false" headerText="col4" id="c5">
<af:outputText value="#{row.col4}" id="ot2"/>
</af:column>
<af:column sortable="false" headerText="col5" id="c2">
<af:outputText value="#{row.col5}" id="ot5"/>
</af:column>
</af:table>
</f:facet>
</af:panelHeader>
