Hmmm... well, since I have almost no Swing experience. :-( IIUC, I would use the event listeners to listen for a click event, and at that point, I would pull in the data for the child nodes in the DB? I'll give that a try today. If I'm on the wrong track, it would be great if somebody could let me know. :-) Thanks again for all the nice work!
