Issue with treetable selection listner in ADF

Question

Hi Experts,
we are working on JDEV 11.1.1.2.
here we have a tree table.
Inorder to get the selected row data in a tree table we are using following code in backing bean.
public void qaTableSelectList(SelectionEvent selectionEvent) {
String selectedQaCode ="";
RichTreeTable treeTable = (RichTreeTable)getQaReasontreeTable();
RowKeySet _selectedRowData = treeTable.getSelectedRowKeys();
Iterator rksIterator = _selectedRowData.iterator();
while (rksIterator.hasNext()) {
List key = (List)rksIterator.next();
JUCtrlHierBinding treeTableBinding =
(JUCtrlHierBinding)((CollectionModel)treeTable.getValue()).getWrappedData();
JUCtrlHierNodeBinding nodeBinding =
treeTableBinding.findNodeByKeyPath(key);
selectedQaCode = nodeBinding.getAttribute(0);
//use this var "selectedQaCode".
Initailly this code are working fine for a long time
Now suddenly its stopped working.
some time its returning the selected value some times not.
What will be the issue can any one suggest alternate solution.
regards
Gayaz

It changed about 2-3 weeks ago.
I haven't done anything to it at all. I just drag an mp3/wav, chop it, save it and I'm done, so I'm not sure why it would all of the sudden change
It's also noteworth that I reinstalled it several times and it hasn't fixed it. Could it be left-over files from the initial install that weren't unistalled and remained, which affected the reinstall? If so, where would I find them?
