Problem in JSF addRemoveList component selection

Question

Hi,
We are using JSF creator studio 2.0. In our project we are using addRemoveList component to display available and selected items.
We are able to display the selected value from available list to Selected list.
uisng Add and remove buttons of the AddremoveList component.
But we are facing the problem is, we are unable to get particular selected or highlighted value from the SelectedList .
However we are able to get all selected items in bakingBean.
This is very very important for us to move further in our development. I really appreciate for any sort of help.
Thanks,
Ramesh

Hey Andy,
I did it that way (JSC 2):
assuming the add remove component's id is arl and that the components' item-property is bound to a datatable (mysql). The value field is of type Long, the display field is of type String.
Get selected:
get an array of selected objects directly from the component, and then do what ever you like to with that array.
Object[] objSel = (Object[]) arl.getSelected();
int i;
int l = objSel.length;
String str;
for (i = 0; i < l ; i++) {
str = objSel.toString();
Set selected:
Just create an array of objects holding the selected values and pass it to the component. But, attention, you'll need to make sure you're feeding the object array with the correct types of values. In my sample the value is a Long as described above, so I also need to pass in a Long, else the component just does nothing at all.
Object[] selObj = new Object[] {new Long(5), new Long(8)};
arl.setSelected(selObj);
I found this the most easy option to get and set the add remove list selection.
An other quite easy option is to bind the selected-property of the component to any session-bean property of type object-array and then set this sessionbean-property to the approrpiate values. But here you need also to make sure the datatype is correct.
