Using Hibernate 3.05, a class with <class ... mutable="false" ... > properly threw on any attempt to delete instances of that class from the database via Hibernate.
After upgrading to Hibernate 3.2.2, Hibernate allows deletion of class instances.
What am I (or, less likely, is Hibernate) doing wrong?
Thanks,
Tom
Code fragment:Code:
final AuditRecord record = new AuditRecord();
// setting of object properties elided
System.out.println("saving");
dao.save(record);
assertThat(record.getPrimaryKey(), NOT_NULL);
System.out.println("removing");
try {
dao.remove(record);
// In Hibernate 3.0.5, an exception is raised here.
// In Hibernate 3.2.2, the instance is deleted
fail("Should raise exception on attempt to delete an AuditRecord.");
}
catch (final Exception e) {
assertThat(e.getMessage(), NOT_NULL);
}
Code in dao.remove() method (extending Spring's HibernateDaoSupport):Code:
public void remove(final Object object) {
getHibernateTemplate().delete(object);
}
Hibernate version: 3.2.2

No exception occurs; this is the problem. ;)
