Hardy Ferentschik commented on HV-526:
--------------------------------------

Your problem is actually due to the usage of 
{code}
	@LazyCollection(LazyCollectionOption.EXTRA)
{code}

the problem is that by using it, the collection is not loaded at once, but via multiple session. In your _B.detach_ you are actually modifying the collection and since you are using _LazyCollectionOption.EXTRA_ the collection becomes dirty and a new event is triggered which in return calls the validator. Your validator itself then forces a initialization of the collection and gets into an endless loop. I think you just cannot use _ at LazyCollection(LazyCollectionOption.EXTRA)_ in this case. I wouldn't consider this a bug in Validator or Core atm.

> Hello,
> I have a stackoverflow error in the following test case.
> This test case define a bidirectionnal relation OneToMany between A and B where at least one B is Required in the collection A.getB().
> The goal of the test case is to delete some B retreived from database.
> My conclusion: it does not work when retreiving B directly - see deleteFromB() - but it works when getting B from the retreived A - see deleteFromA().
> In class MainAB.java, if I use deleteFromA() method, the deletion of "B"s works but deleteFromB() causes a stackoverflow.
> I think it is a bug on Hibernate or Hibernate Validator but I am not sure, perhaps it is normal with this mapping ?
> If someone can guide me.
> Best regards,
> Vincent
