[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-2774) nullpointer on getting context in tomcat 6.0

nullpointer on getting context in tomcat 6.0 -------------------------------------------- Key: JBSEAM-2774 URL: http://jira.jboss.com/jira/browse/JBSEAM-2774 Project: JBoss Seam Issue Type: Bug Components: Core Environment: tomcat 6.0 Reporter: deanhiller Assigned To: Pete Muir Fix For: 2.0.2.GA, 2.1.0.BETA1 seeing as nullpointer's are always bugs(ie. should have a good description of what user did wrong here instead of nullpointer). I think this was caused by my pages.xml file.....specifically..... <page view-id="/web/login/userregister.xhtml" action="#{login.getLoginPage}"> <navigation> <rule if="notLoggedIn"> </rule> <rule if="#{userManagerDo.registered}"> <redirect view-id="/web/login/previewHtml.xhtml"/> </rule> </navigation> </page> When stepping through seam code, I noticed it tends to evaluate all the rules to see if it matches the action if statement(which I don't like because this is before rendering the page). Also, it calls these same rules after the page renders as well which is really confusing. in fact, because of this, userManagerDo.registered fails so I have to delete the action as that rule was meant for an after rending page call like clicking the register button on userregister.xhtml page. instead it calls that before the page is even rendered because of my action....but I think this may be a whole different bug then the one below which is caused by my adding the <rule if="notLoggedIn"> <render/> </rule> Mar 21, 2008 6:01:38 PM org.jboss.seam.jsf.SeamPhaseListener beforePhase SEVERE:
