[cdi-dev] [JBoss JIRA] (CDI-489) NonexistentConversationException thrown at restore view or not?

[Jozef Hartinger (JIRA)]

    [ https://issues.jboss.org/browse/CDI-489?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13013931#comment-13013931 ] 

Jozef Hartinger commented on CDI-489:
-------------------------------------

Yes, it is an outdated Javadoc.

Since CDI 1.1 the conversation context is stared for each Servlet request thus it needs to be restored in the beginning of request processing, before JSF takes control.

> The 1.0 spec says in 6.7.4:
> {quote}If the propagated conversation cannot be restored, the container must associate the request with a new transient conversation and throw an exception of type javax.enterprise.context.NonexistentConversationException from the restore
> view phase of the JSF lifecycle. The application may handle this exception using the JSF ExceptionHandler.{quote}
> 1.1 and 1.2 just say:
> {quote}
> If the propagated conversation cannot be restored, the container must associate the request with a new transient conversation and
> throw an exception of type javax.enterprise.context.NonexistentConversationException.
> {quote}
> Yet the javadoc of NonexistentConversationException for both 1.1 and 1.2 says:
> {quote}
> If the propagated conversation cannot be restored, the container must associate the request with a new transient conversation and throw an exception of type NonexistentConversationException from the restore view phase of the JSF lifecycle.
> {quote}
> So is it supposed to be thrown from restore view or not? I assume not. Probably javadoc should be amended.
> I'm curious about reasoning behind the change. I tried searching for an explanation but didn't find anything.
