---------------------------------------
Any chance of getting this patched in 3.1.4 as well? Thanks.

[Hibernate-JIRA] Commented: (HHH-1196) Avoid unnecessary updates when cascading the deletes
by Frederic Leitenberger (JIRA)
[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1196?page=c... ]
Frederic Leitenberger commented on HHH-1196:
--------------------------------------------
I had the same problem with a much more important problem than an additional sql-statement.
We implemented our own advanced property- and state-transition-validation using hibernate-interceptors.
Property-Validation is done in onFlushDirty and onSave.
State-Transition-Validation ist done in onPreSave, onPreUpdate and onPreDelete.
Short description of the problem:
- save entity and attach childs to it
- flush/commit
- delete and/or detach all childs and delete the entity
- flush/commit
During the last flush/commit the entity is deleted and afterwards updated/flushed before final deletion ...
This produces problems during validation since the current state during flush is almost empty and causes validation to fail.
The state-transition validation fails too, because a delete causes the object to change its state into a wrong state first before finally deleted.
Here are some code nipps and stacks:
All in same session with same entities.
Transaction tx = session.beginTransaction();
E1 entity1 = new E1();
session.save(entity1);

I have an unlucky workaround for now.
I set the version onDelete to null and skip the validation when the version is null (defaults to -1).
Please review/reopen this issue and fix it if possible!!

> Consider this mapping:
> <class name="Category" table="category">
> <id name="id"><generator class="native"/></id>
> <version name="version"/>
> <property name="description" not-null="true" column="description"/>
> <many-to-one name="parent" column="parent_id" cascade="persist"/>
> <set name="children" inverse="true" cascade="all">
> <key column="parent_id"/>
> <one-to-many class="Category"/>
> </set>
> </class>
> Now suppose we have a root category with some children
> and try to delete one of them:
> Category root = ... ;
> Category child = root.children().iterator().next();
> root.remove(child);
> session.delete(child);
> session.flush();
> Hibernate issues these SQL statements:
> - an update for the root entity incrementing the version
> that's ok because the set of children has changed
> - an unnecessary update for the child entity to be deleted
> this update changes no fields (even version) and IMO is unnecessary
> - the deletes for the chilren of deleted child
> That unnecessary update is executed even when deleted child has no children.
> Its children collection is changed from empty set to null
> and that is detected as property change, hence the update.
> A better strategy would be not to update entities that are going to be
> deleted during the flush.
