Nate: If you don't want to extend Tree and override dragEnterHandler, then here's something else to try.
In the tree instance's dragEnter handler, add some data with the format "treeItems" like so: var obj:Object = new Object(); event.dragSource.addData(obj,"treeItems"); It may seem klugey, but it works. -Jim On Tue, 24 Apr 2007 16:59:36 -0000 "Nate Pearson" <[EMAIL PROTECTED]> wrote: > Thanks for the response. > > I've read that document and from what I understand dragEnter doesn't > have to do anything but have the dragmanager.acceptdragdrop.
