You will receive one or two ItemEvents when the selection changes. The first event is "item deselected" (the old selection). If the original selection is empty, you won't receive this event. The second event is "item selected" (only if the new selection isn't empty). [ November 10, 2004: Message edited by: Geza ba ]
