[JBoss JIRA] Commented: (RF-572) ClassCastException when trying to access a JSF Portlet using RichFaces
8:24 a.m.
[ http://jira.jboss.com/jira/browse/RF-572?page=comments#action_12379073 ]
Thomas Heute commented on RF-572:
---------------------------------
MyFaces implementation has a unique FacesContextFactory for Portet and 'pure
servlet' environemnt and check against the 2 to create the
correct FacesContext:
if (context instanceof ServletContext)
{
return new ServletFacesContextImpl((ServletContext)context,
(ServletRequest)request,
(ServletResponse)response);
}
if (context instanceof PortletContext)
{
return new ServletFacesContextImpl((PortletContext)context,
(PortletRequest)request,
(PortletResponse)response);
}
Sun RI has 2 FacesContextFactory, one used in a portlet environment, one used in a servlet
environment both suppose that only portletContext (or only servletContext) will be used,
while this is not the case with RichFaces's filter.
Both implementation are not perfect while the myFaces one is safer as long as no other
context exist. In fact we should have 2 facesContextFactory but the portletContextFactory
should delegate if needed.
As a conclusion on this particular problem it should work just fine with MyFaces but the
jsfportletbridge.dev.java.net project should modify this behavior.
Alternatively we can probably create a RichFacesFacesPortletContextFactory and workaround
this issue

I have created a JSF portlet using the latest RichFaces source code from svn. I have
added a <rich:panel> to my jsp page, deployed it to my jboss portal, created a
portlet instance and added it to a page. When trying to access the page I get the
following stacktrace:
08:37:37,523 WARN [SkinFactoryImpl] Init parameter for a skin name changed to
org.richfaces.SKIN
08:37:39,853 ERROR [[Faces Servlet]] Servlet.service() for servlet Faces Servlet threw
