-----------------------------------------
I agree with your point, it's sad that it's needed to change both parts of the
Java collection, but really that's a limitation of the way collections are used;
Hibernate can't do much about that.
Hibernate will use one or the other collection as "source" to apply
modifications; the most simple strategy for user code to make sure that's going to
happen is to mandate as best practice to always mandate both sides - this point is
strongly stressed at all hibernate courses and books, so your best bet is make sure that
all "helpers" in your code update both sides.
Of course, if you have an idea, we'll be glad to hear about it.
@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).
