                    <logic:notEmpty name="bterm">

Thanks a lot for the help so far, I've created a method to check the basePanel for any components it holds and try to create a JTree display from it. The code I currently have is :
     public void updateObjectSelector()
          // Setup the tree viewer
          DefaultMutableTreeNode root = new DefaultMutableTreeNode(basePanel.getClass());
          addChildren(root, basePanel);
          tree = new JTree(root);
     public void addChildren(DefaultMutableTreeNode root, JPanel parent)
          Component [] children = parent.getComponents();
          for(int i = 0; i < children.length; i++)
               DefaultMutableTreeNode child = new DefaultMutableTreeNode(children.getClass());
               try
                    addChildren(child, (JPanel) children[i]);
               catch(ClassCastException e)
               root.add(child);
basePanel and tree are both global variables. basePanel is the root Panel to which everything is added to.
I am calling "updateObjectSelector()" every time a component is added to the basePanel but at the moment all I can get displayed by the JTree is the getClass() of the basePanel, none of its children are being displayed. Can anyone see what I have done wrong here?
Many thanks again for all your help so far.
