Extend the DefaultMutableTreeNode to have a boolean array flaggin what are the options allowed for that node.
Attach the Popup Listener to this node and check the validity of these options before populating the Popup menu with the options. If valid enable else disable them. That is the simplest approach i can think of.
Hope that helps!!
