Thanks to the injection hint I was able to make my custom NavigationPortlet work which was missing the service injections in the jboss-portlet.xml for the PortalObjectContainer... and: <service-name>PortalAuthorizationManagerFactory</service-name> <service-class>org.jboss.portal.security.spi.auth.PortalAuthorizationManagerFactory</service-class> <service-ref>:service=PortalAuthorizationManagerFactory</service-ref> Posted so anyone trying to do the same will get a hit for this post in a search.
