Hi Brian,
Nice post. Yeah, that is wierd; looks like a bug. You can get around
it for now, by looking at the data instead:
public function handleTreeItemChange(event:ListEvent):void
{
debugTextArea.text = "ListEvent's selectedItem: " +
testtree.selectedit...@label <mailto:testtree.selectedit...@label> ;
}
