title: Smartgwt Drop from listgrid to treegrid
body: <p>I'm trying to get the event when the user left a record from a listgrid on a treenode in treegrid.</p>
  
  <p>I was trying with </p>
  
  <pre><code>ListGrid messagesGrid = new ListGrid();
  messagesGrid.setCanDrag(true);
  
  TreeGrid shortcutsTreeGrid = new TreeGrid();
  shortcutsTreeGrid.setCanAcceptDrop(true);
  shortcutsTreeGrid.setCanAcceptDroppedRecords(true);
  
  shortcutsTreeGrid.addDropHandler(new DropHandler() {
  @Override
  public void onDrop(DropEvent dropEvent) {
         SC.say("drop event is called"); // I want to catch this event
  
   }
  });
  </code></pre>
  
  <p>Please any idea?</p>
