I have installed the portal 2.2 in order to test my portlet that successfully runs under the portal 2.0.1. The first rendering phase succeeds, but I get a NPE performing an action. Is this a bug or I did something wrong migrating from 2.0.1?
java.lang.NullPointerException at org.jboss.portal.portlet.impl.ActionRequestImpl.getPortletMode(ActionRequestImpl.java:45)
