Hi xflin,
It appears that the UIViewRoot is null when it is throwing the
exception. I haven't used your exact configuration, so I'm not sure I
can provide much more help. You might try irc.freenode.net ##jsf.
There are a lot of Facelets users on there... and even Ed Burns (author
of DynaFaces) is there often.
The environment I do use is JSFTemplating + DynaFaces (I've even blogged
about it:
http://blogs.sun.com/paulsen/entry/jsftemplating_dynamicfaces_easy_ajax).
JSFTemplating supports the Facelets syntax now (beta quality) and has
many active developers. I can help you if you end up using this. You
can talk to JSFTemplating developers via IRC at: irc.freenode.net
#JSFTemplating .
Good luck!
