    Error when accessing a JSF portlet via WSRP

    Hans Kohlreiter Newbie

      When I try to access a portlet that uses JSF via WSRP I get a NPE in RenderResponseImpl.getNamespace(RenderResponseImpl.java:134)

      The problem can be reproduced:
      Download the HelloWorldJSFPortlet application from portlet swap
      Add a jboss-portlet.xml to make the portlet remoteable

      <portlet-app>
      <portlet>
      <portlet-name>HelloWorldJSFPortlet</portlet-name>
      <remotable>true</remotable>
      </portlet>
      </portlet-app>
      

      Now deploy the app and create an instance of it using the "self" portlet provider
      Add the portlet instance to a page and try to view it in your browser
      The following exception should occur

      Did anyone know what I do wrong here or is it a JBoss Portal bug??
