ADF Tree Table
I am using JDev 11g.
I created tree table and warped around with toolbar with commandToolbarButton in it. How can I delete leaves or root node? Thanks.
Hi,
to delete a node you need to get the selected node (rowkey and then delete it programatically), get the row it represents and delete it

[SOLVED] Multiple Dynamic View Objects and View Links - ADF Tree Table
Hi all,
I've got a method that creates 3 dynamic viewobjects using this:
ViewDefImpl Level1ViewDef = new ViewDefImpl("Level1View");
Level1ViewDef.addViewAttribute("LevelDescription","LEVEL1_DESCRIPTION",String.class);
Level1ViewDef.addViewAttribute("SetOfBooksId","SET_OF_BOOKS_ID",Number.class);

Level1ViewDef.setBindingStyle(SQLBuilder.BINDING_STYLE_ORACLE_NAME);
Level1ViewDef.resolveDefObject();
Level1ViewDef.registerDefObject();
ViewObject vo1 = createViewObject("Level1View",Level1ViewDef);I can create the view objects fine and create a single viewlink between two of them, however i'm getting problems with 2 view links.
This is how I'm creating a view link:
ViewLink Level2Level1FKLink = createViewLinkBetweenViewObjects("Level2Level1FKLink1",
"Level2View",
vo1,
new AttributeDef[]{
vo1.findAttributeDef("Level1")
vo2,
new AttributeDef[]{
vo2.findAttributeDef("Level1")
"LEVEL1 = :Bind_Level1");
ViewLink Level3Level2FKLink = createViewLinkBetweenViewObjects("Level3Level2FKLink1",
"Level3View",
vo2,
new AttributeDef[]{
vo2.findAttributeDef("Level2")
vo3,
new AttributeDef[]{
vo3.findAttributeDef("Level2")
"LEVEL2 = :Bind_Level2");I can get the data to display on an adf tree table if i'm only using a single view link, but when i try and implement 2 view link (for 3 levels on the adf tree table) i'm getting problems displaying the data.
I'm getting the following error:
Aug 10, 2007 2:44:39 PM oracle.adfinternal.view.faces.renderkit.core.xhtml.PanelPartialRootRenderer encodeAll
SEVERE: Error during partial-page rendering

Question on the ADF Tree Table
Hi, I am using Jdev 10.1.3.2 and ADF BC. I have created a ADF Tree Table to display multiple attributes, both the master and detail VO are based on the same EO. It seems all of attributes are displayed in one colume, and there is no column heading, is that possible to add column heading and display in multiple columns?
Thanks!Hi,
actually the node stamp doesn't accept more than one column element

ADF Tree Table Repeats Elements at All Levels in nodeStamp Facet
Fusion Middleware Version: 11.1.1.5
WebLogic: 10.3.5.0

Hi
I have an issue with ADF Tree Table (af:treeTable) whereby if I add a component to a group under the 'nodeStamp' facet it repeats for all levels in the tree even those outside the group.
Overview:
- 3-level master-detail structure created using ADF Business Components (3 view objects connected by 2 view links)
- ADF Tree Table based on master-detail
- Requirement to show 3 levels of data in the first column as a tree
- Tree table is rendering correctly showing values for 'node.FullName', 'node.DisplayValue' and 'node.HoursType' respectively in a 3 level tree.
- When another component is added to the top node in the tree ('node.FullName') for example some output text ('node.TimeBuildingBlockId'), it is displayed along side components 'node.DisplayValue' and 'node.HoursType' as well.
Code snippet:
<af:treeTable value="#{bindings.PerPeopleFVO1.treeModel}" var="node"
selectionListener="#{bindings.PerPeopleFVO1.treeModel.makeCurrent}"
rowSelection="single" id="tt1" styleClass="AFStretchWidth"

Any ideas greatly appreciated.Hi,
Try using a switcher to distinguish all three levels of a tree. You can have three different facets, three different af:group 's.
When you add in one level, it will not repeat in the other level.
Please see the below snippet.
<af:tree value="#{bindings.RefBusinessUnitView1.treeModel}" var="node"
selectionListener="#{bindings.RefBusinessUnitView1.treeModel.makeCurrent}"
rowSelection="single" id="t1">

Problem in executing Child VO having bind parameter for ADF tree table
In my application i need to show a ADF Tree table which is using two view objects having view links between them
and the child VO has a bind variable.By clicking on the parent node of the parent VO attribute it showing the right result from the child VO attribute by the view link.
I have tried to execute the child VO programmatically (In AmImpl) with the bind variable and using ViewCriteria as well
but both the cases the child vo is not showing the proper result according to the bind variable instead of it is showing all the records on click of the parent node attribute.
Your help will be appreciated.
ThanksHello,
In the same situation I added another relationship to the view link to set the parameter.
Tricky moment is you have to name your parameter like :Bind_ParamName as view link is setting this kind of parameters (check it in Query tab). -
ADF Tree table is not exapanding
Hi all,
I have to implement an ADF tree table along with a form. I have three Views,
two of the views are used to populate the Tree table, And one of the view used in the Tree population is used to manipualte the form,
And the third one is to populate a table. And I have a Popup call button in the same panelCollection where the tree table is placed
I am facing two issues with the the tree table.
1. The tree table is not expanding, if I click on the '+' on the node it won't expand and it will show me small circle which is trying to open the node.
But if I click on the Popup button and cancel(RollBack) the popup and come to the node, it will exapand. I don't kow why it is....
2. As I said I have a Form and I have to populate the form based on the selection in the tree table nodes, the form filed is same as that of the view used to populate the Tree table view.
But when i click on the tree table nodes it is not chaning the record according to the selection in the tree nodes. But in a master Detail form it is working fine. It is always pointing to the first record.
Please help.....No vinod, I am not getting any kind of exceptions..
And mY tree table is

It works with jdev/adf 11.1.1.1.4. only with jdev/adf 11.1.1.1.5 (JDEVADF_11.1.1.5.0_GENERIC_110409.0025.6013) we're having this error. FacilitySummaryVO doesnt have primary key attribute.
Data got populated to VO programmatically
All VO attribute value updatable value is alwaysHi,
hard to say. Actually the "node" variable reference is only available during tree rendering. So if you have any reference to the "node" variable that is invoked after tree rendering then this would explain the exception

ADF Tree Table - Multiple Commandlinks in one column
Hi,
We are building a hierarchy using tree table. The hierarchy looks as follows
+Root Object
++ Child Object One
+++ Child 1.1
+++ Child 1.2
+++ Child 1.3
++ Child OBject Two
At each level, the object is used by more than one users. We want to display the list of users who are using that object in one the column called "Users". We want to provide hyperlink to each of the user that is displayed here. So my question so how do we build set of af:commandlinks with in one column? Or is there any other way this problem can be solved? What is ADF recommended pattern here?
Thanks,How about putting a af:panelGroupLayout in the column and add multiple af:commandLinks into the panel=

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,
KiranHi 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,

How to disable a node in ADF Tree Table?
Hi,
I'm using JDeveloper version - 11.1.1.7
I have a requirement to disable the nodes in Tree table based on status of the node. How can I achieve this?
Any inputs would be helpful.
Thanks
RaviHi,
you cannot disable nodes in the sense that they cannot be expanded or selected. What you can do though is to ignore node selections in a custom selection handler or to render the node different (e.g. using an output text component instead of a command link or image etc.). What is your functional requirement for what disabled nodes should not do

I have a Applications TreeTable and I want to implement QuickQuery on it.. but filtering is not happening on Child VO.
is this possible to implement QuickQuery on Tree Table? if so please provide me some inputs.
JDev Version : 11.1.1.6.0.
Thanks,
SwathiHi Jobinesh,
I have also tested with the sample that is attached in the blog.. the same issue is there.
Steps for the Testcase:
- Run the jsf page and enter sample name (FirstName / LastName) and filter the records.
- records are filtered and displayed.
- Empty the given sample name from the search filed to clear the filter.
- previous search records are displaying with out clearing the search criteria.
this issue is with the sample using ViewCriteria.
sample with the Bind parameters is fine..
Thanks,

Synching ADF tree table and adf tree
Hi,
I am facing issue in syncing the data between adf treetable and tree
Here is my use case
I have one treetable and one tree in the UI..
treeTable shows the hierarchical view and tree represents the flat view of the same data.
If I delete the data in the tree view and then go to treeTable the deleted shows still show in this view and same happens in other case...
Any pointer to this will be of great help
ThanksDo you see that you are using difference object in below table gui def.
snapshotList and snapshotList1.
ADF code:
<af:table value="#{bindings.snapshotList1.collectionModel}"
var="row" rows="#{bindings.snapshotList1.rangeSize}"
emptyText="#{bindings.snapshotList1.viewable ? 'No data to display.' : 'Access Denied.'}"

selectedRowKeys="#{bindings.snapshotList.collectionModel.selectedRow}"
rowSelection="single"
visible="#{viewScope.myBean.isFlat}"
binding="#{viewScope.myBean.table}">
Please generate getter and setter both.
MB code..
private RichTable table;
public RichTable getTable() {
return table;
public void setTreeTable(RichTreeTable treeTable) {
this.treeTable = treeTable;
delete button is outside.. it is in a panelGroupLayout

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.
Please find the Page Definition and Jspx Page Code Below

</af:treeTable>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. -
ADF Tree Traversal from one node to its leafs
Hello,
after a titanic effort I have been able to add a checkbox next to each node of an adf tree table.
This checkbox is based on an "helper" entity attribute (not mapped to a column table on the database).
My next huge problem is to perform an automatic selection of all the checkboxes next to the nodes under the currently selected one.
For example, if the user checks a checkbox in the second level, then all the checkboxes next to the nodes under that, belonging to level three and four must be checked.
If this helps, in my case there are at most four levels.
Up until now I can get all the information from the currently checked node, but I fail to navigate the hierarchy under it for the automatic checking. I think that one problem is to navigate all the rows in the (only) VO the tree is based on. For example, since the tree is not expanded at the beginning, if I iterate on the VO retrieved from the current selected node at the top level, I can't see any rows corresponding to any children. Maybe I just miss something.
I have followed this example from Frank Nimphius, which only gets the current selected nodes, as I said, but no more. Maybe this is a good starting point, but I need to advance somehow.

Can anyone help?
Thanks.Hi,
here is a sample of how to search in trees, which actually shows how to traverse trees from a specific node
http://www.oracle.com/technetwork/developer-tools/adf/learnmore/61search-in-rendered-trees-177577.pdf
Given you have a transient attribute defined, each node (and instance of JUCtrHierNode --> getRow will give you access to the attribute for read/access). Note that because the checkbox is stamped in the context of the tree, upon selecting a parent node, you need to refresh the tree to show the selection state change

Hello,
I am trying to use the ADF tree table for the first time. I have a Master VO and a Detail VO, the Master accepts a bind variable. There is a view link between the master and detail.
When I drag and Drop the executewithparams and create an adf parameter form on my page fragment, the tree table will work as expected when the executewithparams button is clicked. However, I want to use a pageFlowScope variable and invoke the executewithparams, but the Detail VO does not load any data. The Master VO works as expected but there is no rows for the Detail VO when expanded. I am just confused, it works when I execute with an Execute With Params button, but not with an invokeaction. I can see the pageFlowScope values displayed on my page, so I know they actaully have a value.
