Ok, I have now managed to reproduce the problem in a very simple test.
To make things clearer, I have taken out all interceptors and event listeners.
And the test simply retrieves a row and then deletes it.
Now if the test is transactional, then the update occurs before the delete. But if non-transactional, then there is no update before the delete.
I think the difference here will be that when transaction the object is always associated to the hibernate session. But when non-transactional, the object is detached between the retrieve and the delete.
But why this makes a difference I do not know. So can anyone shed some light on this?
Code:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext.xml")
@TransactionConfiguration(transactionManager="transactionManager")
@Transactional
public class TestHibAbcDAO
{
@Test
@Rollback(false)
public void testRetrieveDelete()
{
SjeVO vo = abcDAO.retrieve(new Long(361463));
abcDAO.delete(vo);
}
}
new mapping
