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
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 path 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 )
