I have faced the similar problem using tree2 & facelets.
the version I used is 1.1.5, I think the solution post in
http://wiki.apache.org/myfaces/Use_Facelets_with_Tomahawk is for 1.1.3 and
prior verion.
i have your method below, however it doesn't work for me still, I can only
see the root level, and can't expand the + sign.
Could you post your simple workable version with facelets? reall
appreciated your help!
