I would like to know if you have intention of continuous the integration with facelets (ajax4jsf and facelets)?
Both projects, ajax4jsf and richfaces have built-in facelets support.
Any incompabilites is bug, and must be resolved as fast as possible.
Please, report in JIRA ( http://jira.jboss.com/jira/browse/AJSF ) if you have any problems.
