@ContainedIn does not work on deletes.
--------------------------------------

                 Key: HSEARCH-605
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-605
             Project: Hibernate Search
          Issue Type: Bug
          Components: engine
    Affects Versions: 3.2.1
            Reporter: Kyrill Alyoshin


So, let's say we have a @Indexed entity Vendor (the parent) that is in a bi-directional @OneToMany relationship with entity Address (the child). Vendor maps the collection of Address'es as @IndexedEmbedded. Address is NOT @Indexed but does map its parent vendor association as @ContainedIn. 

Whenever Address entity is retrieved and session.delete'ed, the parent Vendor's index is NOT updated. Everything works fine with update operations. 

This obviously happens because the collection of addresses in parent vendor still contains the deleted address. (If the deleted address is manually removed from collection, everything works fine). 

Now... I realize that it is not in Hibernate style to automatically severe the association when a child entity is deleted. However, it seems that Hibernate Search should provide such functionality. This does lead to very subtle, hard to diagnose bugs. I assume when Vendor's collection is flushed it is fairly trivial to detect which addresses have been deleted and which not (inside the listener).
