Orphaned identities ------------------- Key: HHH-1716 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1716 Project: Hibernate3 Issue Type: Bug Components: core Reporter: James Carman When saving an object, its identity is set (for generated identities of course), even if the transaction is rolled back. This can cause some nasty problems in webapps when using an entity object to store data entered by the user on a form (and displaying back the data if there are errors). Hibernate will think this object is persistent even though it's not when using saveOrUpdate(). Is there a way that the identity values can be set back to what they were originally (nulled out) or can you not set the identity values until transaction completion? Here's some code: final Foo foo = new Foo(); foo.setName( "Hello, Foo!" ); final SessionFactory sf = getSessionFactory(); Session session = sf.openSession(); Transaction tx = session.beginTransaction(); session.save( foo ); tx.rollback(); session.close(); session = sf.openSession(); tx = session.beginTransaction(); session.saveOrUpdate( foo ); tx.commit(); // Exception here! session.close(); sf.close();
