[weld-issues] [JBoss JIRA] Updated: (WELD-214) ServletConversationManager does not serialize properly when the HttpSession is serialized

ServletConversationManager does not serialize properly when the HttpSession is serialized ----------------------------------------------------------------------------------------- Key: WELD-214 URL: https://jira.jboss.org/jira/browse/WELD-214 Project: Weld Issue Type: Bug Components: Built-in beans, Conversations Affects Versions: 1.0.0.CR1 Environment: GAE/J 1.2.5 Reporter: Huy Le Attachments: ServletConversationManagerSerializationTest.java I tried deploying WELD 1.0 CR1 to Google App Engine and got the following stack trace. I suspect that this is probably due to the fact that AbstractConversationManager does not implement Serializable, hence when ServletConversationManager is serialized/deserialized with the HttpSession, none of the fields on AbstractConversationManager is restored. This meant that when cleanupConversation was invoked, the 'currentConversation' field was null. com.sun.faces.lifecycle.Phase handleAfterPhase: JSF1053: (Listener: org.jboss.weld.jsf.WeldPhaseListener.afterPhase(), Phase ID: RENDER_RESPONSE 6, View ID: /home.xhtml) Exception thrown during phase-listener execution: java.lang.NullPointerException com.sun.faces.lifecycle.Phase handleAfterPhase: org.jboss.weld.conversation.AbstractConversationManager.cleanupConversation(AbstractConversationManager.java:132) sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) java.lang.reflect.Method.invoke(Method.java:40) org.jboss.weld.bean.proxy.ClientProxyMethodHandler.invoke(ClientProxyMethodHandler.java:111) org.jboss.weld.examples.numberguess.ServletConversationManager_$$_javassist_1.cleanupConversation(ServletConversationManager_$$_javassist_1.java) org.jboss.weld.jsf.WeldPhaseListener.afterRenderResponse(WeldPhaseListener.java:128) org.jboss.weld.jsf.WeldPhaseListener.afterPhase(WeldPhaseListener.java:99) com.sun.faces.lifecycle.Phase.handleAfterPhase(Phase.java:175) com.sun.faces.lifecycle.Phase.doPhase(Phase.java:114) com.sun.faces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:139) javax.faces.webapp.FacesServlet.service(FacesServlet.java:266) org.mortbay.jetty.servlet.ServletHolder.handle(ServletHolder.java:487) org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1093) com.google.apphosting.runtime.jetty.SaveSessionFilter.doFilter(SaveSessionFilter.java:35) org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1084) com.google.apphosting.utils.servlet.TransactionCleanupFilter.doFilter(TransactionCleanupFilter.java:43) org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1084) org.mortbay.jetty.servlet.ServletHandler.handle(ServletHandler.java:360) org.mortbay.jetty.security.SecurityHandler.handle(SecurityHandler.java:216) org.mortbay.jetty.servlet.SessionHandler.handle(SessionHandler.java:181) org.mortbay.jetty.handler.ContextHandler.handle(ContextHandler.java:712) org.mortbay.jetty.webapp.WebAppContext.handle(WebAppContext.java:405) com.google.apphosting.runtime.jetty.AppVersionHandlerMap.handle(AppVersionHandlerMap.java:238) org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java:139) org.mortbay.jetty.Server.handle(Server.java:313)
