It seems in Sun's infinite wisdom that a node in a JTree must have at 
least 1 child in order for there to be an expansion control next to the 
node. I don't want to load my tree structure all at once and so I'm 
getting each node's children a node at a time when it is either selected 
or expanded. But I still want the stupid expansion control so I'm 
creating a fake node temporarily.

This does the job except that when a node is expanded for the first time 
I get a quick blink where the dummy node is being deleted before the 
real nodes show up.  I don't know why this happens since I'm only 
reloading the tree at the selected node one time so I was wishfully 
thinking that I wouldn't even notice 1 node being removed and a bunch of 
others being added but I do.  Do I have to go to the trouble of creating 
my own tree expansion listener (disable the listener, then remove the 
dummy node, reload the tree at the selected node, add the real nodes, 
then enable the listener and reload again?) just for this stupid little 
feature that should already be there?  What can I do to fix it?

thanks
