title: Detect drop target node in a sencha ext-gwt 3.0 tree
body: <p>Context: sencha ext-gwt <strong>3.0</strong> (beta3). I am using dnd to let the user re-arrange a tree, one element at a time. I can easily get the dragged element but didn't find how to get the drop target. Here is my code:</p>
  
  <pre><code>final TreeDropTarget&lt;IMyModel&gt; target = new TreeDropTarget&lt;IMyModel&gt;(mytree);
  target.setAllowSelfAsSource(true);
  target.setAllowDropOnLeaf(true);
  target.setFeedback(DND.Feedback.BOTH);
  target.addDropHandler(new DndDropEvent.DndDropHandler()
  {
    @Override
    public void onDrop(final DndDropEvent event)
    {
      IMyModel dragged = mytree.getSelectionModel().getSelectedItem();
  
      // TODO get the drop target element!
    }
  });
  </code></pre>
