Hello, Thank you very much. I tried to add this: <application> | <variable-resolver> | org.jboss.seam.jsf.SeamVariableResolver | </variable-resolver> | <locale-config /> | </application> to my faces-config.xml and this is what I get: 14:38:21,015 ERROR [D2DFaceletViewHandler] Error renderResponse.

I also tried to add a Seam servlet filter (org.jboss.seam.servlet.SeamServletFilter) around the Persistent Faces Servlet. I would like to understand how these two frameworks are supposed to interact with one another. Could you please explain me (basically) how it should work ? which servlet is to be called first ?
