Try this code as a dragDrop event handler for the tree and let me know if it doesn't work.
 
 
function doDragDrop(event) {
   doDragExit(event);
 
    var items = event.dragSource.dataForFormat(treeItems);
 
   var dest = event.target;
   var dropLoc = dest.getDropLocation();
 
   dest.clearSelected();
   var dropParent = dest.getDropParent();

   for (var i = items.length - 1; i >= 0; i--)
   {
    var newNode = dropParent.addTreeNodeAt(dropLoc,items[i]);
    dest.selection = newNode;
   }
  }

Subject: [flexcoders] Tree Drag and Drop help

I've been wracking my brains on this for a while now, and it hasn't
been a smooth ride. Instead of chanting my experiences in this forum,
it all boils down to my pleading for help from any of you.

Can anyone please provide me a code sample or a URL of such
pertaining to drag-n-drop with a Tree which can demonstrate a
successful drag of one node onto another, and having the dragged node
appear as a child of the node where it was dropped?

In a nutshell, I've gotten as far as getting the node references of
the dragged and dropped nodes within my dragDrop event, including the
index of the node that was dropped on. I can even display these two
nodes using "alert", and their internal toString() methods would
correctly display all the node contents (in XML). However, when I use
the addTreeNodeAt() method on a node that's a parent (i.e. a folder),
nothing happens! And when the node is a leaf (i.e., not a parent of
any child nodes), that node somehow "climbs" up one step higher in
the tree hierarchy, and the dragged node does not appear anywhere!

I would be very grateful to anyone who could provide me some help and
guidance on this please. :(
