10.1.3.3 ADF BC:How to get a value of from a LOV that uses a fixed list?

Question

Hi,
I create a dropdowlist on a JSP based on a list of items I type in. It's called " fixed List" I think instead of dynamic list which is from a DB table.
In order to add a valuechangedlistener to the dropdownlist, I need to get the real value of the selected item on the list. I've changed the autosumit to true. Use this line I can get an object of a FaceCtrlListBinding.
FacesCtrlListBinding TdIter = (FacesCtrlListBinding)bc.get("LandLegalView1Td");
When value changed, I get only get the new index of the selected item. I tried to use TdIter.getAttributeValue(index) and it returns me null. I also tried TdIter.getAttributeFromRow(index,"Td") and it returns me null, too.
Could someone share some idea, Please? Thank you very much.
Regards,
Annie

Frank,
Thank you very much for your reply. I've set "valuePassThrough" property of the dropdownlist to true. In the valueChangeListener, my code looks like this.
public void TD_valueChangeListener(ValueChangeEvent valueChangeEvent) {
System.out.println("+++++++++");
System.out.println("TD_valueChangeListener");
Number n = null;
BindingContainer bc = this.getBindings();
if(bc != null){
System.out.println("bc is not null");
//get the selected TD
FacesCtrlListBinding TdIter = (FacesCtrlListBinding)bc.get("LandLegalView1Td");
if(TdIter != null){ 
System.out.println("TdIter is not null");
if(valueChangeEvent.getNewValue() != null)
try{n = new Number(valueChangeEvent.getNewValue());}
catch(Exception e){
e.getMessage();
System.out.println("selected TD index="+n);
//Object td = TdIter.getAttributeFromRow(n.intValue(), "Td");
Object td = TdIter.getAttribute(n.intValue());
System.out.println("real value of td=" + td);
}else{
System.out.println("TD is null");
}else{
System.out.println("TdIter is null");
My question here is: I tried two ways of getting the real value of the new selected value. One is "Object td = TdIter.getAttributeFromRow(n.intValue(), "Td");". The other is "Object td = TdIter.getAttribute(n.intValue());". None of them give me the new selected value but the old value. Did I do anything wrong?
