Hello. I have to make some additional code changes in project, which is built on jboss portal. Deployment is ok, but when I try to refres localhost:8080/portal page after deployment I get this:

java.lang.ClassCastException: org.jboss.portlet.JBossRenderResponse cannot be cast to javax.servlet.http.HttpServletResponse

This exception occurs in PhaseListener:

FacesContext facesContext = event.getFacesContext();
HttpServletResponse response = (HttpServletResponse)facesContext.getExternalContext().getResponse();

Here is configuration:
portlet.xml:

<portlet-app
 xmlns="http://java.sun.com/xml/ns/portlet/portlet-app_1_0.xsd"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

jboss-portlet.xml:

<?xml version="1.0" encoding="UTF-8"?>
<portlet-app>
 <portlet>
 <portlet-name>SomePortlet</portlet-name>
 <header-content>
 <link rel="stylesheet" type="text/css" href="/css/styles.css" title="" media="screen"/>
 </header-content>
 </portlet>
</portlet-app>

And finally:
MyFacesRepairedPortlet:

public class MyfacesRepairedPortlet extends MyFacesGenericPortlet{

 protected void facesRender(RenderRequest request, RenderResponse response) throws PortletException,
 java.io.IOException {
 if (sessionTimedOut(request) || request.getPortletSession().getAttribute(CURRENT_FACES_CONTEXT) == null) {
 setPortletRequestFlag(request);
 nonFacesRequest(request, response);
 return;
 }

 super.facesRender(request, response);
 }


}

Please help!!
With Best Wishes, Maxim
