According to the JSF 2.0 spec, ui:component and ui:fragment do not have a "rendered" attribute. Yet Mojarra supports it, and so does the original facelets implementation. In fact, the only usecase that I have seen for ui:fragment is to conditionally render one. Is this a spec error? If so, I'll be glad to file an issue. Thanks, Cay -- Cay S.
