I reported the problem here.
http://issues.apache.org/jira/browse/MYFACES-1570
I don't know how to fix it, though, other than to use facelets (which
has its own issues with tree).
You might want to downgrade to an older version of MyFaces Core until
it's fixed. The change that broke it occurred in Oct 2006.
