Hardy Ferentschik commented on HV-586:
--------------------------------------

I think you just found the answer to your question yourself. _ at NotEmpty_ will initialize the proxy, because it needs to check the size of the set.

One solution could be to map the collection extra lazy (Hibernate specific feature) in which case only the size of the collection gets queried:

{code}
class A {
   @OneToMany
   @LazyCollection(LazyCollectionOption.EXTRA)
   @Valid
   @NotEmpty
   private Set<B> b;
}
{code}

I think you still will need a open session though. This is something which is always needed when working with lazy collections.

> I use hibernate validator for detached entities, some of them are not initialized. If they are not initialized imho there is no possibility that they could have been changed so that constraints might be broken. Although hibernate validator goes for them and I get LazyLoadingExceptions.
> Also this is a change to previous versions. Has that been done on purpose?
