[jira] [Updated] (MYFACES-3530) Implicit Navigation Does Not Work
After ViewExpiredException
[ https://issues.apache.org/jira/browse/MYFACES-3530?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Paul Nicolucci updated MYFACES-3530:
------------------------------------
Status: Patch Available (was: Open)
> Implicit Navigation Does Not Work After ViewExpiredException
> ------------------------------------------------------------
>
> Key: MYFACES-3530
> URL: https://issues.apache.org/jira/browse/MYFACES-3530
> Project: MyFaces Core
> Issue Type: Bug
> Components: JSR-314
> Affects Versions: 2.0.13
> Environment: MyFaces 2.0.13 running on WebSphere Application Server
> Reporter: Paul Nicolucci
> Attachments: NavigationHandlerImpl.diff, NavigationHandlerImpl.txt, NavigationHandlerImplTest.diff, NavigationHandlerImplTest.txt, ViewExpiredException.war
>
> Original Estimate: 4h
> Remaining Estimate: 4h
>
> When implementing a Custom ExceptionHandler to deal with ViewExpiredExceptions as suggested here: http://weblogs.java.net/blog/edburns/archive/2009/09/03/dealing-gracefully-viewexpiredexception-jsf2
> The implicit navigation to "viewExpired" does not work due to the fact that a "/" is not added to the "viewIdToTest" in NavigationHandlerImpl.getOutcomeNavigationCase. The algorithm was correct until we pulled in MYFACES-3101 to avoid
> a NullPointerException after a ViewExpiredException.
> The exception we see without the patch is the following:
> [4/19/12 20:52:15:323 EDT] 00000028 webapp E com.ibm.ws.webcontainer.webapp.WebApp logServletError SRVE0293E: [Servlet Error]-[Faces Servlet]: org.apache.myfaces.lifecycle.ViewNotFoundException: A view is required to execute RENDER_RESPONSE(6)
> at org.apache.myfaces.lifecycle.RenderResponseExecutor.execute(RenderResponseExecutor.java:62)
> at org.apache.myfaces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:239)
> The view does exist but is no longer found since we don't add a "/" since the viewId is null.
> I've also added a couple of additional "null" checks that look to have been missed in MyFaces-3101.
> A test Application will be provided as well as a diff showing my changes to NavigationHandlerImpl.java and NavigationHandlerImplTest.java ( the ViewExpiredException test needs to look for /viewExpired not viewExpired after the fix...which to me seems correct )
