Hi there,

I'm working on a client/server project where the client side app has a
JTree.  I am trying to set up a TreeModel so that it retrieves from the
server app the names of the child nodes of a given node when the
treeWillExpand(TreeExpansionEvent tee) method gets triggered.  So far I've
accomplished this.  In my TreeModel class I have a method called:

ReceiveChildrenFromServer(DefaultTreeNode parent, String ParentsWholePath,
DataInputStream input)

This method does what it is supposed to, however, once it has populated the
parent node, I expected the JTree to display the nodes.  This is not
happening.  Can someone please explain how I get the JTree to then display
the child nodes.

Thanks,

Alan
