Null Pointer Exception in MyFacesGenericPortlet ----------------------------------------------- Key: JBPORTAL-530 URL: http://jira.jboss.com/jira/browse/JBPORTAL-530 Project: JBoss Portal Issue Type: Bug Security Level: Public(Everyone can see) Environment: Jboss 4.0.3 SP1 - portal 2.0.1 RC3 Reporter: Stefan Tausendpfund Priority: Minor Fix For: 2.6.Beta1 Attachments: DuplicatePortletTestWeb.tgz Hello, the initial post is from the Jboss portal forum. I repost it to attach a sample application showing this error. <snip> Hello, we created an portal application on JBoss Server 4.0.3SP1 with portal 2.0.1RC3 using myfaces MyFacesGenericPortlet. We have several pages and several portlets in one page. One portlet is present in all pages. If I make an action on this portlet (portletwindow0) and switch the page (portletwindow1) i get an NPE in the facesRender method of the MyFacesGenericPortlet. The lookup of the faces context with ServletFacesContextImpl facesContext = (ServletFacesContextImpl)request. getPortletSession(). getAttribute(CURRENT_FACES_CONTEXT); returns a null object and the following statement if (facesContext.getResponseComplete()) return; fails. On first entry of doView the getAttribure looks for an Attribute: javax.portlet.p..<portletwindow0>?org.apache.myfaces.portlet.MyFacesGenericPortlet.CURRENT_FACES_CONTEXT After switching the page it looks for javax.portlet.p..<portletwindow1>?org.apache.myfaces.portlet.MyFacesGenericPortlet.CURRENT_FACES_CONTEXT but the facescontext is still with the key window0 in the session. Using the same window name in different pages for the same portlet leeds to a portal error. <snap> best regards Stefan Tausendpfund
