[JBoss Seam] - Re: JPA/Hibernate Entity: broken identity between Entity & O

by pierospinelli

Ok Andy, first of all many thanks for your reply. What you wrote is very interesting, but I am not sure about a point: I understand I can get two objects for the same entity during the same request due to some implicit flush before a query (I think this behaviour is controlled by hints), but wouldn't the flushed objects have to return false at EntityManager.contains? The problem is that I got two "valid" objects for the same entity, that is both contained by the same EntityManager at the same moment. It seems I found a way to fix it by a better implementation of the methods: compareTo, hashCode and, overall, equals in all my entities, even those I have to navigate to get the duplicated instances: so my understanding (but I ask for confirmation), is that the identity within an EntityManager is kept by using equals and not (as I believed having used some JDO implementation) by using the pair class/id. I don't know if it depends on a specific implementation, but I think it should be well defined in the JPA standard (I know, this forum could not be the right place for the discussion), since it could have some side effects, or (at least) it would require a more detailed specification about the canonical ways to implements equality, hashing and ordering for the entities.

[JBoss Seam] - Re: Activation of SFSB and removal of it by Seam question

by pete.muir＠jboss.org

You will get an exception. If you can put something simple together that reliably shows this, then create a jira issue and we can take a look.

[JBoss Seam] - Re: TestNG entityMnager question

by pete.muir＠jboss.org

Sorry, didn't read your post carefully. I don't see why you need to init the entity manager in the Java SE fashion if you are using SeamTest.

[JBoss Seam] - Re: Persistence EJB Hibernate JDO

by pete.muir＠jboss.org

persistence.xml is for JPA/EJB3 so not relevant for JDO. Yes, you could probably use Seam with JDO but I don't know of anyone doing it. Seam shouldn't need JPA or Hibernate to run, so report issues here. But you will loose a lot of the power of Seam as there is no integration.

[JBoss Seam] - Re: Custom Validator? How?

by pete.muir＠jboss.org

Post the source for validator, you probably need to implement Stateholder. You are probably better off asking in a JSF forum as this is pure JSF.

Alternatively define a second SMPC in components.xml from the same jndi lookup for the Persistence Unit factory.
