Subject CDI event propagation to ViewAccessScoped/ConversationScoped classes
Date Tue, 08 Oct 2013 14:05:00 GMT
Hello,

I have a database layer, that can be accessed by JSF and by REST. The
backing beans for JSF are ViewAccessScoped. The services for REST are
RequestScoped.

When creating an entity, from both JSF or REST, an event should be raised
to notify all possible clients (JSF, but also other clients listening e.g.
JMS events). Now a problem occurs. When I create an entity using the REST
interface the event is raised as expected.

However now WELD raises an ContextNotActiveException:

org.jboss.weld.context.ContextNotActiveException: WELD-001303 No active
contexts for scope type
org.apache.myfaces.extensions.cdi.core.api.scope.conversation.ViewAccessScoped

I get the same problem when using the ConversationScoped annotation. This
problem occurs always when using the REST interface, i.e. whether or not I
have an JSF page open.


Below you find a more detailed stack trace starting from the point where
the event is fired.It seems like Weld thinks there is such a bean, but in
the end then can't get a context.

What can I do here? Does the CODI implementation even work in this context?

If you need more information about my setup, let me know :)

Regards,
Boris
