[hibernate-issues] [Hibernate-JIRA] Commented: (HSEARCH-460) LazyInitializationException while removing entity with @ContainedIn annotation

[Maciej Szulik (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-460?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=35905#action_35905 ] 

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.

>             Project: Hibernate Search
>          Issue Type: Bug
>          Components: engine
>    Affects Versions: 3.1.1.GA

>            Priority: Blocker

> 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.
