Can you explain more detailed what is not working?
Does it crash? In which line? You can use print statements to find the line.
Or does it not select the item? If so, does it execute the path you
expect? Also verify this with print statements.
For the functionality you want to implement, I see a problem with the
KeyListener. What if text is changed by drag and drop or the mouse
context menu "paste"?
I think the VerifyListener would be good choice.
