Ansynchronous tree table selection listener in ADF ?
Hello,
We have a tree table in our jsff on which user can select and right click nodes.
The code in selectionListener takes a long time to execute. At the end it raises a contextual event which refreshes another part of the screen
User needs to wait for the selectionListener, and the ppr of another region of the screen before he can get the context menu on right click
Is there a way we can configure the selectionListener and subsequent Contextual Event handler, ppr to be asynchronous.
Expected Flow
Select Row
selectionListener starts..
Right Click Row
Context Menu appears .....
Contextual Event handler completes, ppr of another region of screen completes
Any pointers ?

Tree Table Selection after deletion
Hi,
We have a tree table where we are displaying hierarchy of information. We have a "Delete" operation. This operation is available in the context menu associated to each node. When user selects "Delete" operation, the selected row is deleted and the next node is automatically selected. We have implemented a selection listener on this table but when this automatic selection happens after deletion this event is not triggered. How do we trigger the selection event after deletion? We require the selection event because, we are keeping track of the selected nodes. Even for delete, we are identifying the item to be deleted from the list of tracked nodes. When this auto selection happens and the user clicks delete menu, the auto selected row it is not available in the tracked list as the selection listener is not fired for the auto selection.
Can any throw some light on how to address this?
thanks,Hi,
what if - after deleting a node - you call for the selectedRowKeys on the tree to get the new selected row. This way you can update what otherwise the listener does.

Hi,
I wold like to know if there is any way that I can invoke #{bindings.myVO.collectionModel.makeCurrent} from the backing bean. Thanks.
Regards,
K.HeinHi,
yes, you can. Just use a method expression
FacesContext fctx = FacesContext.getCurrentInstance();
ELContext elctx = fctx.getELContext();
ExpressionFactory expressionFactory = fctx.getApplication().getExpressionFactory();
expressionFactory.createMethodExpression(elctx, "#{bindings.myVO.collectionModel.makeCurrent}", Object.class, new Class[]{SelectionEvent.class}).invoke(elctx, new Object[]{selectEvent});Frank

Getting NullPointerException in ADF form using Custom Selection Listener
Hi,
I am getting NullPointerException from getRowKey() in GenericTableSelectionHandler.java while pressing "Page Down" key or continuous pressing of "Down Arrow" key in Read Only ADF form (Query, Sort Enabled) using Custom Selection Listener.
I have used the custom selection listener as mentioned at http://www.oracle.com/technetwork/developer-tools/adf/learnmore/23-generic-table-selection-listener-169162.pdf
The requirement to use custom Selection Listener to populate some fields from the selected row.

Hi,
I have a treetable in panelGroupLayout with scroll layout.When scrolling down to the end,some treetable row doesn't appear...That is,panelGroupLayout scrollbar is not synchronized with treetable.But with mouse wheel,i can scroll down to the end of treetable rows.Why?Thanks in advance...Timo:
I have some related observations.
I am using jDeveloper 12c and JSE-JDK 7 Update45
( and Windows 8.1 Professional, includng latest updates and
a standard logitech wired mouse, model M110 ).
I have a database and application module.
The next step is Creating A Databound Web User Interface.
And, I have created TWO of them as follows...
1) Chapter 31.3.1 How to Display Master-Detail Objects in Tables and Forms Using Master-Detail Widgets
http://docs.oracle.com/middleware/1212/adf/ADFFD/web_masterdetail.htm#ADFFD761
Here, I am choosing "ADF Master Form, Detail Table “.
TESTING SUCCEEDED.
The detail tables scroll successfully using the mouse (or scroll bar).
2) Chapter 31.5.1 How to Display Master-Detail Objects in Tree Tables
http://docs.oracle.com/middleware/1212/adf/ADFFD/web_masterdetail.htm#ADFFD775
" The steps for creating an ADF Faces databound tree table are
exactly the same as those for creating an ADF Faces databound tree, except that
you drop the data collection as an ADF Tree Table instead of an ADF Tree.
For more information, see Section 31.4.1, "How to Display Master-Detail Objects in Trees."
http://docs.oracle.com/middleware/1212/adf/ADFFD/web_masterdetail.htm#BJEJBGCI
TESTING FAILED:
The detail tables fail to scroll using the mouse (or scroll bar).
I've been looking at this problem for a day or two (or three) and
I just don't have any warm fuzzy feelings on how to resolve this.
While I am delighted that the Form-Table interface works well,
I really really like the Tree-Table interface, a lot !
If others could share their Tree-Table observations, that would be wonderful. -
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,
TomoHi 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 Header -->
The listener is now always getting the currently selected row only.

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:column>
</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. -
How to display the path of selected node of a tree table.
Hi,
I have one use case where I have to display the path of node of tree table which is selected one.
e.g.
Suppose the tree table is like this.
Folder1(root)
->folder2
->folder3
->folder4
Now when I select this folder1 then path display should be "/folder1(root)"
when i select the folder4 then path should be "/folder1(root)/folder3/folder4"
Hope this one will help to understand my use case..

ADF Tree Table Repeats Elements at All Levels in nodeStamp Facet
Fusion Middleware Version: 11.1.1.5
WebLogic: 10.3.5.0
JDeveloper Build: Build JDEVADF_11.1.1.5.0_GENERIC_110409.0025.6013
Project: Custom WebCenter Portal Application integrated with custom ADF task flows.
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"
horizontalGridVisible="true" verticalGridVisible="true"
disableColumnReordering="true" summary="Timecard Entry"
displayRow="selected" expandAllEnabled="false"
contentDelivery="immediate" autoHeightRows="24"
columnStretching="column:column1"

<f:facet name="nodeStamp">
<af:column id="c1" headerText="Partner Details" width="500">
<af:group id="g4">
<af:outputText value="#{node.FullName}" id="ot3"/>
<af:outputText value="#{node.TimeBuildingBlockId}" id="ot1"/>
</af:group>
<af:outputText value="#{node.DisplayValue}" id="ot4"
inlineStyle="color:Green; font-weight:bolder;"/>
<af:outputText value="#{node.HoursType}" id="ot5"/>

</af:column>
</f:facet>
<f:facet name="pathStamp">
<af:outputText value="#{node}" id="ot2"/>
</f:facet>
<af:column FROM HERE.........>
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">
<f:facet name="nodeStamp">
<af:group id="g1">
<af:switcher id="s1"
facetName="#{node.hierTypeBinding.viewDefName}">
<f:facet name="model.RefBusinessUnitView">
<af:group id="g2">
<af:outputText value="#{node.Code}" id="ot1"/>
</af:group>
</f:facet>
<f:facet name="model.RefProductFamilyView">
<af:group id="g3">
<af:outputText value="#{node.ProductFamilyName}" id="outputText1"/>

I created ADF Query Panel with Tree Table using JDeveloper 11G. Under Advance Search, Add Fields pull down only list the fields in the master table. My questions are,
1) Can I search fields in detail table? If yes, how can I do it?
2) How can I customized this pull down list? Currently it just show the entire view of master table with unnecessary id type data.
Thanks in advance.

Are there anyway to search the second level node?You can. But you need to evaluate if the arrangement works for you.
I assume you have a view link from the master to detail VO.
To do so, in your master view criteria (the one which you use in the query panel), shuttle the attributes of your detail VO (in master attributes list, you'l see the detail view link accessor - on selecting this, the detail atteributes are available to you)
In the Add Fields, it shows as student_id AND student_name. I was unable to delete the student_id field in the view since it is PKYou can set its 'display' UI hint to 'hide' in your VO. -
Creating a generic selection listener for af:table
Hi,
I'm using JDeveloper 11.1.1.5.0, and I have a simple requirement to set up a custom selection listener for an af:table component.
So far, I was doing this by using a custom function to invoke the EL to perform the makeCurrent operation. However, I came across Frank Nimphius' PDF on how to build a generic selection listener, and this seemed like a better way to go about it. The problem is, the CollectionModel class used in the sample code is now deprecated. Is anyone aware of the currently supported way to implement a generic selection listener?
Thanks,
Gillthis snap shot of the code i write it to get the current employee id whcich is selected
public void select(SelectionEvent selectionEvent) {
// Add event code here...
RichTable _table = (RichTable)selectionEvent.getSource();
CollectionModel _tableModel = (CollectionModel)((RichTable)selectionEvent.getSource()).getValue();
JUCtrlHierBinding _adfTableBinding = (JUCtrlHierBinding)_tableModel.getWrappedData();
DCIteratorBinding _tableIteratorBinding = _adfTableBinding.getDCIteratorBinding();
//Acess the ADF iterator binding that is used with ADF table binding
Object _selectedRowData = _table.getSelectedRowData();
JUCtrlHierNodeBinding _nodeBinding =
(JUCtrlHierNodeBinding)_selectedRowData; //get the row key from the node binding and set it //as the current row in the iterator
Key _rwKey = _nodeBinding.getRowKey();
_tableIteratorBinding.setCurrentRowWithKey( _rwKey.toStringFormat(true));
DCIteratorBinding it = _adfTableBinding.getDCIteratorBinding();
System.out.println( it.getCurrentRow().getAttribute("EmployeeId"));
}this code i written 11.1.2 -
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
<af:treeTable value="#{bindings.TestVO.treeModel}"
var="node"
selectionListener="#{backingBeanScope.TestBean.TreeTableSelectionListener}"
rowSelection="single" id="tt1"
columnStretching="column:c1" contentDelivery="immediate"
binding="#{backingBeanScope.TestBean.tt1}">
<f:facet name="nodeStamp">
<af:column id="c1">
<af:panelGroupLayout id="pgl15">
<af:outputText value="#{node.SubtaskDesc}" id="ot1"/>
<af:outputText value="#{node.HazardDesc}" id="ot4"/>
</af:panelGroupLayout>
</af:column>
</f:facet>
<f:facet name="pathStamp">
<af:outputText value="#{node}" id="ot2"/>
</f:facet>
<af:column id="c2">
<af:outputText value="#{node.MaxRiskRating}" id="ot3"/>
</af:column>
</af:treeTable>

Problem getting the Table Data with the selection listener
Hi All,
I am working on a tree and table components. I wrote a logic in the backing bean in such a way that when I expand a node the child nodes for the tree are getting added dynamically and also getting the data in the table for the node expanded in the tree using the same Toplink Query . I added the selection listener for the table and when I am selecting a row in the table I am getting the Null Pointer Exception as the RowKeySet Value for the row selected is coming null.
Can any one please help me out with this problem
I will be very thankful

How can I do that.
If anyone know it, please help me
Thanks in advance.<af:table value="#{bindings.BuddyView1.collectionModel}" var="row" partialTriggers="id"
rows="#{bindings.BuddyView1.rangeSize}"
emptyText="#{bindings.BuddyView1.viewable ? 'No data to display.' : 'Access Denied.'}"
fetchSize="#{bindings.BuddyView1.rangeSize}"
rowBandingInterval="0"
selectedRowKeys="#{bindings.BuddyView1.collectionModel.selectedRow}"
*selectionListener="#{bindings.BuddyView1.collectionModel.makeCurrent}"*
rowSelection="single" binding="#{backing_untitled1.t1}"

You will have to create your own selection listener method.

Af:Table retains rows selected and selection listener doesnt work
Hi
I have a table with a list of objects passed to it to be rendered. When the user selects an object and clicks on the launch button above the table, it launches a new page and on the new page when the user clicks on cancel it brings back to the same page where the table is present. While coming back to this page, the row that was earlier selected by the user is highlighted and a click on the same row doesnt enable the selection listener. I have to click on some other row and then click the old row if I want to relaunch the old page
<af:table var="row" rowBandingInterval="0" id="tblProcedures" emptyText="#{dbProcedureMsg.TABLE_EMPTY_TEXT}"
summary="#{dbProcedureMsg.TABLE_SUMMARY_TEXT}"
value="#{pageFlowScope.db_provisioning_DeploymentProcedurePageModel.collectionModel}" filterVisible="false"
columnStretching="column:colDescription" rowSelection="single" width="99.7%"
selectionListener="#{pageFlowScope.db_provisioning_DeploymentProcedurePageModel.processSelection}">
There is one more table which behaves the same way. But other tables which are part of my application work correctly.
Any idea on what I might be doing wrong ?
Thanks in advanceHi,
To be honest Million rows in excel its questionable for me
I would try to find alternate solution rather than killing ADF on client and then your DBA will call you for a urgent meeting. Even if you make it work with ADF, people will not going use it due to huge amount of data load.
What you can do is to call external report like Jasper, BIRT etc. etc. and provide option there to export to Excel based on your criteria (but million rows is again questionable)
OR
one idea is to give option at client side to request a report with button at af:TABLE toolbar ...then you can schedule a job at database server level using PL/SQL dbms_scheduler package with OS script to generate text file on server and FTP it to some machine.
Hope it help,
ZB
