The RichFaces EPVC in RF 4.5 extends the JSF PartialViewContextWarpper
The PVCWrapper implements the setPartialRequest method  as defined in
the PVC abstract class . This wrapper method was added in JSF 2.2.
Since you are targeting EAP, I suspect you are compiling with JSF 2.1 in
which case this method is not implemented in the wrapper . We should
then copy the implementation to our EPVC. Can you file a jira for this?
