That's exactly what it's supposed to do.  You get one for the item
that is getting de-selected (it's state changed) and one for the item
getting selected (it's state changed).  You need to do your own
filtering in your events so that your code executes only when you want
it to.  Something like:

void choiceChanged(ItemEvent e){

 if(e.getStateChange() == ItemEvent.SELECTED){
   // do whatever
 }

}

If you see something that looks like an opinion up there,
it's mine and mine alone.

Mail sent to me from the newsgroups won't bounce but will
be ignored.  If I have time, I'll respond, but you  have
a better chance if you confine your posts to the newsgroups
