Hi -
I've read about Seam's support for an extended persistence context, and have read
about Seam conversations. I've got a Lazy Initialization problem that doesn't
seem to quite fit the solutions I've read about - maybe I just can't quite see
it.
I've got an entity object with a lazy loaded collection. The entity has Session
scope, and is created early in the application. The main page of the app has a link that
the user can click at any time that displays a Richfaces modal panel form used to modify
the property values in both the entity object as well as its collection. Everything
displays fine in the modal panel, so the collection is loaded successfully by hibernate.
However, when I try to save any changes with a button click on the form and a bean save
action using a stateful session bean, I call entityManager.merge(myEntity), and that's
where I get a LazyInitializationException. All values both in the entity and the
collection are correct in the entity, but I guess since the object is no longer attached
to a hibernate session, the merge does not work.
Is there a preferred way to attach this object to a hibernate session without explicitly
using code to get a session, start a transaction, etc.? From what I've read, this is
of course a common pattern, but the solutions seem to involve more explicit coding than I
would expect to have to do.
This is my first Seam project, so maybe there's a quick, easy solution here that will
get me past this sticking point. I can provide a few code snippets, but I think this is
such a common problem, I'm betting I won't need any.
