Thanks Andrew and Bill for the suggestions. I thought Andrew's idea was great and I went ahead and tried it. It worked well. But I could not get the screen to refresh right after the user click the radio button. I set up break points in the getChildren() and getChildrenCount() methods, and found that they called countless times. I decided it is safer to update tree data instead.
Thanks a lot for sharing.

That way is more of a business logic and UI separation.

Just don't return the node you don't want to show in the getChildren() method and don't count it in the getChildCount() method. AFAIK, there is no way to do it in the XHTML/JSP.
