Yes, check to make sure that crossContext="true" is set in your context
configuration xml in tomcat. If it's not, cross context dispatching
won't be allowed. This null pointer reminds me a little more of the
issue that I just referenced in the last email I sent. . .

Hi All,
I'm deploying a portlet based on the Hepper's HelloWorld example book.
The deployment happens fine but when the portlet is shown, I get the
following error on the browser:
HelloWorld
HelloWorld view | max min nor
Error occurred in portlet!
And in the log files I get:
SEVERE: Error in Portlet
