Nicklas Karlsson commented on WELD-461:
---------------------------------------
What is the stack trace on failure? Is it from the conversation context being destroyed
twice and the BeanStore being null? One option would be to move the destruction flag into
the conversation manager and have it reset when the conversation is set up.
WeldPhaseListener should only cleanup response once
---------------------------------------------------
Key: WELD-461
URL:
https://jira.jboss.org/jira/browse/WELD-461
Project: Weld
Issue Type: Bug
Components: Web Tier integration (JSF, JSP, EL and Servlet)
Affects Versions: 1.0.1.Final
Reporter: Dan Allen
Priority: Minor
FacesContext#getResponseCompete() may be true on more than one invocation of
WeldPhaseListener#afterPhase(). Since the phase listener does not check to see if the
request has already been cleaned up, Weld fails on the second cleanup attempt.
How does this scenario happen? One case is when the application calls
ExternalContext#dispatch() to forward to another view. When the dispatch happens, the
current lifecycle is marked FacesContext#responseComplete(). Control turns over to the
lifecycle of the dispatched request. When the response is complete in that request, the
WeldPhaseListener#afterPhase() will be called with FacesContext#getResponseComplete()
equal to true. Control returns to the original request lifecycle,
WeldPhaseListener#afterPhase() will again be called with
FacesContext#getResponseComplete() equal to true.
The WeldPhaseListener should check to see if cleanup has already occurred, skipping
cleanup if it has.
Applications should not expect contexts to be active in the original request lifecycle
after ExternalContext#dispatch() has been called.
