-----------------------------------------
Summary: 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
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}}:

{{That line has LOGGER.info("Annotated: {}", injectionPoint.getAnnotated()),
and {{injectionPoint}} is null.}}
Maybe this is a separate bug?
If I understand this correctly, my problem would be solved if my custom
resolver would be used for lookups, but the only reference to it is from
{{EntityManagerRefLookup#lookupReference}}, and that just got removed from
{{TransactionStrategyHelper}}.
