Hey all,
I'm working on redirecting a user to the page they requested after
successfully authenticating. To do this I use the
ExternalContext.redirect() method to redirect to a URL that is stored in
the session when they try and access a page but aren't logged in and are
redirected. As I understand the JSF specs, this method should call the
FacesContext.responseComplete() method and JSF shouldn't try and do
anymore with the response. I also have a navigation rule defined for
the case when a user hasn't tried to access something before
authenticating so they get directed to a default pre-login page.
It seems that when a user has tried to access a restricted page without
authentication the navigation handler is ignoring the call to
FacesContext.responseComplete() and trying to do another redirect to the
default pre-login page. This results in the following exception
(somewhat shortened for brevity):
java.lang.IllegalStateException

Is this a bug in the NavigationHandler implementation? I'm using
MyFaces 1.0.9.
I tried returning null from my action handler rather than something
matching a rule to try and bypass the NavigationHandler, but that
resulted in the following exception (again, shortened for brevity):
java.lang.IllegalStateException: Cannot forward after response has been

Any ideas?
