Hello,

I believe I have a simple problem.  I have created a JTree and inserted into
a JFrame.  Two of it's functions are  Copy and Move.  Both work properly on
the JTree itself but neither show the results visibly with in the JFrame.
The first time I Copy a node to another node, the result of the copy will
show up on the JTree. The next time I Copy to that same node, the results
will not show up in the JFrame.  I have to rebuild the JTree in order to see
the results of the copy.  The same thing happens when I Move one node to
another node, except it doesn't even show the results the first time.  Again
I have to rebuild the JTree in order to see the results of the move.

Question:

Does anyone know the proper sequence of commands to tell a given node how to
re-expand itself an show all of it's children nodes, even newly added ones,
on a JTree, with in a JFrame?

Below is the block of code that moves on node to another node.

 // Keeps track of the current selected DefaultMutableTreeNode.
 protected DefaultMutableTreeNode selectedJTreeNode;

 Action moveAction = new AbstractAction("Move"){
    public void actionPerformed(ActionEvent e){
      if (aNodeSelected = true)
       return;
     else
     {
       try{
         TreePath movePath = jTree.getLeadSelectionPath();
         DefaultMutableTreeNode jTreeNode = (DefaultMutableTreeNode)
jTree.getLastSelectedPathComponent();
         selectedJTreeNode.setParent(jTreeNode);
         jTree.expandPath(movePath);
         jTree.repaint();
       }
     }
   }
 }

Thank you to any one who can offer any concrete help.
