Mark Struberg commented on OWB-337:
-----------------------------------

This is exactly where we would need to only have 1 ConversationContext instance which we could ask for isActive()...

> If someone fires an Event, we currently deliver it to all contextual instances of beans which are registered for that event, even if those beans are in a context which is not active yet.
> This happens for example in the following situation:
> A 
> UserLogOutFilter implements javax.servlet.Filter
>  sends a UserSettingsChangeEvent.
> A @ConversationScoped MyBusinessBean @Observes UserSettingsChangeEvent.
> But at the time the servlet filter does run, there is no active ConversationContext yet. This leads to the following Exception:
> javax.enterprise.context.ContextNotActiveException: WebBeans context with scope type annotation @ConversationScoped does not exist within current thread
> 	at org.apache.webbeans.container.BeanManagerImpl.getContext(BeanManagerImpl.java:279)
> 	at org.apache.webbeans.event.ObserverMethodImpl.notify(ObserverMethodImpl.java:201)
