[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-613) search by criteria with sub-class Example do not bind sub-class properties

Paul Benedict commented on HHH-613:
-----------------------------------

Ah. I see. If you create a criteria of the supertype and make an example of the subtype, it obviously will not work. As Gavin said, this is correct behavior. You need to actually create an example of the subtype.

> class Pet extends Animal {
>   private String name;
>   ...
> }
> Pet pet = new Pet();
> pet.setName("Fritz");
> session.createCriteria(Animal.class).add(Example.create(pet)).list();
> This will simply return all 'Pets', no binding occurs with the "name" property of Pet.
> This could, more probably, occurs if I have some Country which contains Animals & I want to look for some kind of Pets in that country :
> session.createCriteria(Country.class).createCriteria("animal").add(Example.create(pet)).list();
