[QA of JBoss Portal] - IPC using MyFacesGenericPortlet
by jnoronha＠systime.net
Hi!!
I want to design a portal app in which there will be two portlets. One will act as a left hand navigation. The second one will be a MyFacesGenericPortlet Instance.
To acheive it I have coded on the lines of the code, used in the example provided at http://anonsvn.jboss.org/repos/portletswap/portlets/2_4/bundles/HelloWorl....
Here the second portlet is a GenericPortlet instance and works fine. The moment it becomes a MyFacesGenericPortlet instance it throws an exception
java listed below:
ERROR [[/myPortal]] Exception in FacesServlet
java.lang.NullPointerException
