Hi

I need help with my jTree.


I create root node with two lower level

I fill the last level (DefaultMutableTreeNode child1) With the function
"public void createNodes(DefaultMutableTreeNode top)".

Now I will save the ID from the Database for every Item in the Jtree.
and will get the ID back with a Doppelkick at the Item.

How can I do this ?????????????????


Please help me !!!!!!!!!
