[flexcoders] Can anyone help me with Drag and Drop for a tree control in Flex 2.0?

[chrislpigg]

I'm trying to get a node when dropped to demote and to become a child.
 I've looked and tried everything.  If anyone could help or give me a
quick example I would appreciate it... very much so.

So far I have a simple tree structure as such.
var temp:String = "<root label=\"Default Policy\">"+
                        "<node label=\"node1\"/>"+
                        "<node label=\"node2\"/>"+
                        "<node label=\"node3\"/>"+
                        "<node label=\"node4\"/>"+
                        "<node label=\"node5\">"+
                   "</root>";

I want to be able to drop node1 on node3 and for node1 to become a
child of node3.
