Hello everyone!

I've got an exception calling saveOrUpdate method after deleting and object. The following example demonstrates the problem

public class HiberTest {
public static void main(String[] args) {

Dumb dumb = new Dumb();
DumbDao dumbDao = new DumbDao() {
public void saveOrUpdate(Dumb obj) {
getHibernateTemplate().saveOrUpdate(obj);
}

public void delete(Dumb obj) {
getHibernateTemplate().delete(obj);
}
};
dumbDao.setSessionFactory(HibernateUtil.getSession Factory());
dumbDao.saveOrUpdate(dumb); // (1)
dumbDao.delete(dumb);
dumbDao.saveOrUpdate(dumb); // (2)
}

private static class DumbDao extends HibernateDaoSupport {
public void saveOrUpdate(Dumb obj) {
getHibernateTemplate().saveOrUpdate(obj);
}

public void delete(Dumb obj) {
getHibernateTemplate().delete(obj);
}
}
}

After the last call I get

Exception in thread "main" org.springframework.orm.hibernate3.HibernateOptimi sticLockingFailureException: Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1; nested exception is org.hibernate.StaleStateException: Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1

I guess that the problem is that at point (1) and (2) objects have the same ids. Am I right? But I think that Spring must handle such situation. Is this a Spring bug or I've missed smth?
