Task #55953: Repair and streamline ValueObject support
Fix OneTo* associations from ValueObjects
ValueObjects are reusable (or reused) from a relational database point of view, i.e. they have a unique constraint. Having a ValueObject referencing other entities with a OneTo* association will fail if another instance of the valueobject intends to reference the same object: there will be a unique constraint error because the object occurrs twice then.
Maybe the Driver should make a ManyTo* out of these.
