FULL PRODUCT VERSION :
java version "1.4.2_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_06-b03)
Java HotSpot(TM) Client VM (build 1.4.2_06-b03, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
I have a menu item with the accelerator CTRL-X. When pressind this key comination while a tree node is being edited and its name is selected within the editor component the following actions occurr:
1. the string in the textfield will be cutted (and is now in the clipboard)
2. the menu item is triggered.

Case 1 is the expected and correct case, but case 2 is a bug, because the textfield has already handeled the key event (the menu item should not be triggered anymore).

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Start the class attached. Select a treenode and click again into this node so that editing starts. Then select some text and press the key combination 'CTRL-X'. Now you will see that the selected text will disappear and that some text is being printed to standard out

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
the string is cutted and the menu item is not triggered
ACTUAL -
the string is cutted and the menu item IS triggered

REPRODUCIBILITY :
This bug can be reproduced always.
