I have a project (EJB 3.0 packaged as an EAR) with presentation layer (JSF 2.0) and persistence (JPA 2.0, Hibernate). To avoid lazy initialization support and other problems, I tried to introduce a Context while retaining Seam Managed Persistence with Seam 3.0.0.Final. For this, I wrote the following class of manufacturers:
import javax.enterprise.context.ConversationScoped; import javax.enterprise.inject.Produces; import javax.persistence.EntityManagerFactory; import javax.persistence.PersistenceUnit; import org.jboss.seam.solder.core.ExtensionManaged; class PersistenceProvider { @ExtensionManaged @Produces @PersistenceUnit @ConversationScoped private EntityManagerFactory producerField; }
And changed @PersistenceContext Annotation to my EntityManager fields on @Inject.
If Iam tries to use EntityManager, now I get the following stack:

Debugging applications on Glassfish 3.1 provided me with the following information
Object Manager is a proxy server of type
entityManager SMPC-org$jboss$seam$persistence$ManagedPersistenceContextExtension-com$example$PersistenceProvider$producerField[@javax$enterprise$context$ConversationScoped()@javax$enterprise$inject$Produces()@javax$persistence$PersistenceUnit(name=,unitName=)@org$jboss$seam$solder$core$ExtensionManaged()]_$$_WeldClientProxy
The producer field cannot be found in beans -Field BeanManager as part of the org.jboss.seam.persistence.ManagedPersistenceContextBeanLifecycle.getEntityManagerFactory method, but in the BeanManager introduced in my DAOs.
I tried some options, for example, to qualify the producer field, trying to implement the entity manager in presentation-level services and add unitName and / or the name of my persistence unit to the @PersistenceUnit Annotation of the producer field.
Any suggestions on what I'm doing wrong here?
