Dear Experts,
I am using JTree to hold some selection possibilities.
I would like to respond to selections and perform some operations.
However, none of the event handlers are ever reached.

FocusGained, MouseReleased, ValueChanged, and KeyReleased


I am using Netbeans 6.5 with Java 1.6. or so

Any ideas how I can fix this problem?

Did you add the handlers to the object(s)?

I merely used the Netbeans facility to add the handlers.
but it seems that Netbeans does add it:

        jTree1.addTreeSelectionListener(new javax.swing.event.TreeSelectionListener() {
            public void valueChanged(javax.swing.event.TreeSelectionEvent evt) {
                jTree1ValueChanged(evt);
            }
        });

On second thought you are right.
I create a new tree and I did not add the listeners again.

Right on CEHJ!
