Hi All,
   I'm learning Swing.

Googling for "nodeChanged TreeModel" lead me to Sam's article of
9 Sep 1998 07:24:39 GMT in comp.lang.java.gui, where he wrote:

I tried to implement my own TreeModel and added the following methods
among others to it:

       public void nodeChanged(Object node) {
           this.fireTreeNodesChanged(new TreeModelEvent(
                   this,
                   ((User) node).getPath()));
       }

       public void fireTreeNodesChanged(TreeModelEvent e) {
           Enumeration listeners = this.treeModelListeners.elements();
           while (listeners.hasMoreElements()) {
               TreeModelListener listener = (TreeModelListener)
                       listeners.nextElement();
               listener.treeNodesChanged(e);
           }
       }

The client tree which uses my own implementation of the TreeModel
interface, used to work properly using the DefaultTreeModel.
But after the switch over to my TreeModel, a call of
treeModel.nodeChanged(theChangedNode) doesn't have any effect anymore.

Any ideas what could be wrong?

Kindest Regards,
