Why the custom SelectionListener not working on a data-bound table?

Question

I followed this Re: How to get query table current row? to customize a SelectionListener on a table as following:
public void mySelectionListener(SelectionEvent selectionEvent) {
invokeMethodExpression("#{bindings.MyVO.collectionModel.makeCurrent}",
Object.class,selectionEvent.getClass(),
selectionEvent);
DCIteratorBinding voBinding = getItrtBindings("MyVO1Iterator");
Row currentRow = voBinding.getCurrentRow();
Object pAttr = currentRow.getAttribute("PoNo");
Object bcAttr = currentRow.getAttribute("BcId");
During runtime, I noticed the following messages showing up on the console when I selected a row on the table
Nov 11, 2009 1:07:33 PM oracle.adfinternal.view.faces.model.binding.FacesCtrlRangeBinding$FacesModel getSelectedRow
WARNING: ADFv: rowIterator is null.
Nov 11, 2009 1:07:33 PM oracle.adfinternal.view.faces.model.binding.FacesCtrlRangeBinding$FacesModel makeCurrent
WARNING: ADFv: No row found for rowKey: null.
When I debugged the selection listener, the "currentRow" always point to the 1st row regardless what I actually selected on the table.
What is missing in my view object that make the selection listener failed to find the current selected row?
I checked my view, there are two key fields defined in the view.

Hi,
The code seems to be fine for me, worth to check following things:
- Have you bound the custom selection listener to the selectionListener property of table?
- Are the iterator names and the EL expression given for makeCurrent inside custom selection listener correct?
- Is rowSelection property of table set to "single"?
Sample Code:
<af:table value="#{bindings.MyVO.collectionModel}" rowSelection="single" selectionListener="#{Bean.mySelectionListener}" ...>
</af:table>Sireesha
