Do CDI beans need to be @ApplicationScoped for errai to use?

[craiggreenhalgh]

I see all the examples use @ApplicationScoped beans.

I would like to use requestScoped if at all possible?

The problem I have with @ApplicationScoped is that I inject a @Stateless EJB which in turn fires an "Authenicated" event.  I have a @SessionScoped bean that observes this event.  When my Errai CDI bean is @ApplicationScoped i get the following error when the event is fired:

Caused by: org.jboss.weld.context.ContextNotActiveException: WELD-001303 No active contexts for scope type javax.enterprise.context.SessionScoped

Any ideas?

Thanks

Errai 1.2.3-SNAPSHOT has support for @SessionScoped. We don't currently support @RequestScoped. Can you describe why you'd prefer @RequestScoped in your scenario or is @SessionScoped solving you problem?

Hi thanks for your reply.

Is the setup different in 1.2.3-SNAPSHOT ?

When I change my CDI bean that Observes GWT events to SessionScope, neither an injected bean (SessionScope) or my Events (Event<ResponseEvent> responseEvent) are injected?

Any ideas?

Thanks for your help

You could use the latest version of the Errai CDI archetype:

mvn archetype:generate -DarchetypeGroupId=org.jboss.errai -DarchetypeArtifactId=errai-cdi-archetype -DarchetypeVersion=1.2.3-SNAPSHOT -DarchetypeRepository=https://repository.jboss.org/nexus/content/repositories/snapshots/

There's also a demo using the latest CDI features ( https://github.com/errai/JBWDemo ) which you can take a look at to compare your setup.

Replacing @ApplicationScoped with @SessionScoped in this example works fine.

Hi Christian,

Yes using the snapshot and sessionbean has solved my issue.

The reason for wanting to use requestscope is realy so the app is as lightweight as possible and a mass of session beans are not hanging arround.

Many thanks again for your help
