One step forward: The exception occurs in this method of class PagePortletControllerContext | protected Portlet getPortlet(String windowId) throws PortletInvokerException | { | WindowDef windowDef = prepareResponse.getWindowDef(windowId); | | //this crashes with a NullpointerException: | return findPortlet(windowDef.getApplicationName(), windowDef.getPortletName()); | } | | //find portlets: | public Portlet findPortlet(String applicationName, String portletName) | { | return portlets.get(new Key(applicationName, portletName)); | } | | How can I make an entry in the portlets-Map????? Either the application name or the portletName seems to be null. regards, rene View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4161991#...
