I solved a similar situation by writing a class that implements
MutableTreeNode (called ElementTreeNode, and giving it an Element as its
user object. I had to implement the various methods of MutableTreeNode,
but this was not so difficult. Somewhat harder was the custom TreeModel
populated with ElementTreeNodes, but there are plenty of resources out
there for dealing with custom tree models. If you have any questions,
Ill be happy to help!
