NPE in clustered setup when rendering portal navigation ------------------------------------------------------- Key: GTNPORTAL-650 URL: https://jira.jboss.org/jira/browse/GTNPORTAL-650 Project: GateIn Portal Issue Type: Bug Affects Versions: 3.0.0-Beta05 Reporter: Prabhat Jha Fix For: 3.0.0-GA Pasting what Marek wrote in mailing list: I founded NullPointerException during failover testing. Steps to simulate exception 1) Going to http://localhost:8080/portal/public/classic 2) Login as root 3) Going to http://localhost:8080/portal/public/FailoverPortal/ (Second portal in my environment) Now it can be seen that page is broken (screenshot attached to this mail) and Exception is in server log (stacktrace attached to this mail). This exception occurs for me only when running GateIn with clustered profile (-Dexo.profiles=cluster). It's ok with default local profile. My configuration-jboss.properties are also attached. I tried to look at cause of this problem. It seems that Util.getUIPortalApplication().getUserPortalConfig(), which is called from UIUserToolBarSitePortlet.getPageNavigation, returns instance of old UserPortalConfig, which has references to PortalConfig and navigations of old portal (portal "classic" in my case). And I founded that: - in local (nonclustered) profile, if logged user switch from one portal to second in his browser, then LegacyPortalStateManager.restoreUIRootComponent is creating new instance of UIPortalApplication() with new UserPortalConfig() and bound it to current PortalRequestContext. Then everythink is fine and no exception occured. - on cluster profile, new UIPortalApplication() is not created when user swith from one portal to another. Because in ReplicatingStateManager.restoreUIRootComponent() is new instance of UIPortalApplication() created only if user login to portal or logout from portal. So old UIPortalApplication is still bound to portalRequestContext and navigations for old portal are returned later in UIUserToolBarSitePortlet.getPageNavigation() . So method UIUserToolBarSitePortlet.getPageNavigation() return null in this case and NPE is here. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
