action performed bug?

[Perica Milosevic]

While working with JButton class I experienced this problem:
The method ActionPerformed is executing twice instead of once like it
should normaly be.
I cannot find out the reason why it's happening. Anyone can help?

Make certain you aren't adding the listener twice.

Make certain you aren't adding the listener twice.

Sorry, I didn't mention that it's not happening each time. Actually, there's
no rule if ActionPerform is executing once or twice. Normally, it's
executing once, but SOMETIMES, which is very rare, it's executing twice.
Therefore, I cannot find out what's actually going on...

Sounds like some sort of race condition. Very tough nut to crack...

Radis u JBuilderu, sa GUI editorom?
Provjeri da li dvaput dodajes listenera, kao sto je vec netko rakao... kad
si siguran da nije to , onda tek trazi dalje jer je to najcesci razlog ove
greske. A JBuilder zna dodati dvapit listenera ako radis sa GUI
dizajnerom...

ActionPerformed is executing twice

there is debounce logic in your mouse driver. Do any other apps act
as if you had hit the button twice? If you hit the mouse tentatively
you might effectively hit it twice.
