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

[Paul Benedict (JIRA)]

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

I'd like to know why this is correct behavior. I also am trying to perform sub-criteria on a polymorphic association. I really am looking for a particular type, and I have not read anywhere -- at least from what I can find -- why this isn't supported. Is it a technical limitation? A philosophical limitation? Time constraint?

>   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();
