        <description>
        A very common problem in configuring MyFaces-web-applications
        is that the Extensions-Filter is not configured at all
        or improperly configured. This parameter will check for a properly
        configured Extensions-Filter if it is needed by the web-app.
        In most cases this check will work just fine, there might be cases
        where an internal forward will bypass the Extensions-Filter and the check
        will not work. If this is the case, you can disable the check by setting
        this parameter to false.

I am using primefaces 2.0.0 Rc

Answer 1

I'd assume version mismatch between primefaces and JSF. For Primefaces 2.0 I think you need JSF 2.0
