Hi, I'm using jboss 4.0.3SP1 with jboss portal 2.2.1-GA and jdk 1.5.0_05. I've got the InterPortlet Communication example working, but when I do a call to WindowActionEvent getParameters() I get the following error: 2007-02-21 10:53:33,650 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/portal].[PortalServletWithPathMapping]] Servlet.service() for servlet PortalServletWithPathMapping threw exception java.lang.NoSuchMethodError: org.jboss.portlet.event.node.WindowActionEvent.getParameters()Lorg/jboss/portal/server/util/Parameters; Any help would be appreciated.
