Yes, I agree. I had raised this issue during spec development - that there was no truly
stateless scope in CDI, where the bean instance was created every time.
I would like to hear from the 299 EG about this as well.

I think that there is a real use case for something similar to the
@Unwrap feature of seam 2.
I think that it would be possible to implement something like this:
@ConversationScoped
public class ManagedPersistenceContext
{
EntityManager entityManager;
@Unwrap
@SomeQualifier
public EntityManager produce(InjectionPoint injectionPoint)
{
entityManager.joinTransaction();
return entityManager;
}
}
public class MyClass
{
@Inject @SomeQualifier EntityManager entityManager;
}
the way I envisage this working is that a proxy gets injected into MyClass, and this
proxy calls ManagedPersistenceContext.produce to resolve the correct EntityManager to pass
the call to every time a method is invoked on the proxy.
I am pretty sure I can implement this in weld-extensions using JDK proxies, does this
sound like a good idea?
