How to avoid updating of the referenced entity, when the owning side gets changed?

[automatix]

Hello!

I have two entities: Foo and Bar with a unidirectional ManyToOne relationship between them (Bar has Foo).

When I try to re-/unset Bar#foo, Doctrine tries not only change the reference (change/reomve the value in the column bar.foo_name), but also to UPDATE the value of foo.name.

In my case it leads to an Integrity constraint violation error. But even if not -- it's not the expected behavior.

Is it a bug or a layer-8-issue? :)

Requires test case, see https://github.com/doctrine/doctrine2/tree/master/tests/Doctrine/Tests/ORM/Functional/Ticket for examples

I wrote a test and have just opened a pull request. The test is working, so it won't be a Doctrine issue. I'm closing this issue. But, anyway, if you have an idea, what it might be caused by, it would be nice, if you share your thoughts about it. Thanks.
