Select correlation wrongly tries to load data based on null correlation basis #724
Description
Description
When having a correlation in e.g. a subview and that subview object is null because the association is null, SELECT fetching fails with an exception, saying that a null id is invalid for EntityManager.getReference(). Obviously, we need to skip correlating when the correlation basis is null.
