-------------------------------------
Resolution: Not A Problem
> TransactionalInterceptor should use the EntityManagerResolver for lookups

> Key: DELTASPIKE-1350
> URL: https://issues.apache.org/jira/browse/DELTASPIKE-1350
> Project: DeltaSpike
> Issue Type: Improvement
> Components: JPA-Module
> Affects Versions: 1.8.2
> Reporter: Andrei Ivanov
> Priority: Major
>
> Hi,
> I'm trying to use the transaction support from the JPA module with multiple
> entity managers that are created by a producer defined in a separate/common
> module.
> That means that any specific qualifiers defined in the client modules (like
> {{@DbA}} / {{@DbB}}{{ from the examples) are not visible to the producer. To
> make this work, I've followed the approach from the
> EntityManagerFactoryProducer}} and I've defined my own qualifier,
> {{PersistenceContextName}}, duplicated from {{PersistenceUnitName}} (and
> similar to the {{CustomQualifier}} from the example).
> I've also created an {{EntityManagerResolver}} in one of the client modules
> and configured it in the DAOs inside it (which are not DeltaSpike
> repositories), with {{@Transactional}} and
> {{@EntityManagerConfig(entityManagerResolver =
> BranchManagementResolver.class, qualifier = PersistenceContextName.class)}}
> As far as I see, only the {{qualifier}} attribute is used, but it invokes my
> producer with a {{null}} {{InjectionPoint}}:
> {noformat}
> java.lang.NullPointerException: null
