LazyInitializationException while removing entity with @ContainedIn annotation
------------------------------------------------------------------------------
Key: HSEARCH-460
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-460
Project: Hibernate Search
Issue Type: Bug
Components: engine
Affects Versions: 3.1.1.GA
Reporter: Maciej Szulik
Priority: Blocker
Attachments: hibsearch.zip, Lazy.stack
I attach a Jboss Seam 2.2.0.GA project (without lib directory - one should take it
entirely from seam default application generated using seam gen), as a complete
illustration of the problem.
The Problem itself:
I have 2 entities:
Color (Long id, String name, Set<Vehicle> vehicles)
and Vehicle (Long id, String name, Color color).
Vehicle is indexed entity (@Indexed), while color has @ContainedIn on Set<Vehicle>.
Problem arises while managing color objects, strictly speaking while removing colors,
LazyInitalizationException is thrown (stack trace is in attachment).
Every other operation on color entity (inserting, updating) works like a charm.
In attached example I created with a simple page for managing colors. It presents a list
of already defined color objects in DB. If non present, you should generate some with
'Add random color'. To obtain above error click on 'Remove' link next to
one of the colors presented on list.

-------------------------------------------
Are you able to create a self contained Search specific unit test. The stack trace
indicates a session management problem not a Search specific problem. You need a open
session when indexing occurs.

Maciej Szulik commented on HSEARCH-460:
---------------------------------------
I'm 1000% sure that this is session management issue and that indexing should occur
inside the session. But I'm not managing the session by myself - application container
is responsible for that (In my case it's JBoss).
Also I cannot isolate the problem, because of the need for application container. Of
course you can throw all the JBoss Seam specific code and leave pure EJB's and the
problem will remain, because the session is managed by container not me! If I'm wrong
feel free to correct my way of thinking.
The problem didn't exist for me in previous versions (namely 3.0.1.GA), because the
mechanism didn't work at all, I had to manually invoke reindex, and then I always
retrieved the session if one wasn't available. Now I can't even override the
default behavior without downgrading.

---------------------------------------
I've tried you proposition and I'm afraid that didn't do the trick.
The problem is with session management and how hibernate search access objects in
session.
It can be handled by adding proxy objects initialization like this:
{code}
Color colorToRemove = em.merge(color);
Hibernate.initialize(colorToRemove.getRzeczy());
em.remove(colorToRemove);
{code}
But above solution is unacceptable from my point of view!

The thing is, at this stage (beforeCompletion) the session is supposed to be opened (and
HSEARCH relies on it). I cannot find why it is not.
