search by criteria with sub-class Example do not bind sub-class properties -------------------------------------------------------------------------- Key: HHH-613 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-613 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.0.5 Reporter: Foaloke Priority: Blocker class Animal { private Int age; ... } 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();
