> In CDI 1.0, the Conversation Scope has extremely limited availability. It is accessible from after RESTORE_VIEW phase in JSF, to the end of the Response, but this is extremely limiting, and in fact does not even address all use-cases within JSF.
> For instance:
> User has custom PhaseListener for Before RESTORE_VIEW phase, or user has custom PhaseListener that invokes before ConversationPhaseListener.
> In said PhaseListener, user attempts to access a ConversationScoped bean.
> ContextNotActiveException results, even though there may be a valid CID in the Request URL
> Example 2:
> User attempts to access ConversationScope outside of the JSF lifecycle (Via EL in a Servlet or ServletFilter, for instance.)
> ContextNotActiveException results, this just doesn't work!
> There is no reason why the ConversationScope should be any less available than the RequestScope, since both depend on the same underlying context objects. (Request, Session, etc)
> ConversationScope should be ubiquitous in the Servlet Container Request/Response lifecycle. This will greatly improve ability to use CDI in view/web frameworks other than JSF.
