[flexcoders] Re: DrangEvent: copy by value instead of reference

Fri, 19 May 2006 07:47:40 -0700

I had tried that as well:

public function handleSelectedItemsDragComplete(e:DragEvent):void {
  var copy:* = ObjectUtil.copy(DataGridItemRenderer(e.draggedItem).data);
  DataGridItemRenderer(e.draggedItem).data = ""> }

For some reason, the object dropped is still pointing to the same
memory location as the original. It's like the item gets dropped
before this listener is called.

I had made a mistake in my initial post. I'm calling this handler on
the dragDrop event but I've also called it on dragComplete (which
doesn't even seem to call the handler.. my debugger never hits the
breakpoint). I also tried it on dragEnter but the draggedItem is null
at that point for some reason.
