[weld-dev] RquestScoped not active inside WeldInitialListener.requestDestroyed

Hello Matej

I spoke to the customer, who kindly provided the following source on 
github: https://github.com/elexx/was9_bugs/tree/master/bug21

It looks like the code is bound to a @PreDestroy method on the 
@SessionScoped annotated class UserSessionData. The PreDestroy fires 
because session.invalidate() is called in LogoutServlet. 

Looking at 
http://docs.jboss.org/cdi/spec/1.2/cdi-spec.html#request_context it 
doesn't seem like any of the four cases when the spec applies here. We 
have left LogoutServlet's service() method before the new thread calls the 
preDestroy method. So I think this is an application issue. 

Regards
Benjamin

Hi,

what does user code look like?
Does he have an event listener?

I'd say this depends on *precisely* what is his code bound to.
At some point (after the invalidation), you should be getting 
ContextNotActiveException so I guess we need to know more about the code 
to determine this.
If the user has some code bound to "generic" servlet events, it may well 
happen that they fire after CDI events.
