dynamically removing leaf from Jtree

Hi all,

I am writting a Jtree that needs to do the following.
1)When a node is expaneded a leaf is displayed say "Loading Please Wait".
2)The system the loads the data
3)Once loaded the "Loading Please Wait" is removed
4)New children are then added to the expanded node.
However I have a small problem:
I using a TreeExpansionListener and have the following code.

However the new leaf "loaded" is not displayed.
I first but this down to the probelm that the tree was not being repainted. So I added tree.validate() and tree.repaint() but that did not help. So thinking it was a problem with my load code I removed that to. I am sure that the node I am removing and adding the leaf to is correct. Has anyone got any ideas?
