I decided to post the code. I just saw your comment about the "new entity ..."
and that does explain part of it (purchase not saved ) as you will see. That
does not explain why the changed entity (member) did not get saved. Member was
injected in the calling SLSB using SEAM and passed to this method.
If it is true that a new entity is not saved on exit that needs to be
emphasized in documentation. I started with the trailblazer and use the
references. Maybe it is in there but I never noticed it.
public @Stateless class PurchaseCreditsBean implements PurchaseCredits {
@PersistenceContext
EntityManager em;
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
public void purchaseCredits(Member member, int purchaseQty)
{
Purchase purchase = new Purchase();
purchase.setPurchasedCredits(purchaseQty);
member.setCredits(purchaseQty + member.getCredits());
purchase.setMember(member);
purchase.setPurchasedCredits(purchaseQty);
em.merge(purchase); // TODO should not have to call merge
em.merge(member);
}
}
Thanks, my assumption is the SEAM injected entity is behaving as if it is not
attached to my em as well. If this is the case I certainly misunderstood
this. I bet many others have been down this same path!
