Saving not working with proxy objects #49

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Try to save an hibernate proxy object not in the Session. Here is a test
case : 

    public void testUpdateProxy() throws HibernateException, SecurityException,
            NoSuchMethodException {
        initDB();
        Address address = papaA.getHome().getAddress();
        try {
            Serializable id = address.getId();

            // When working with 2 differents session, the session.contains(entity)
returns false
            // see in _exists(Object entity) in HibernateBaseDAO 
            SessionImplementor openSession = (SessionImplementor)
target.getSessionFactory().openSession();

            Address proxy = (Address) JavassistLazyInitializer.getProxy(
                    Address.class.getName(),
                    Address.class,
                    new Class[] { HibernateProxy.class },
                    Address.class.getMethod("getId"),
                    Address.class.getMethod("setId", Long.class),
                    new AnyType(Hibernate.LONG, Hibernate.SERIALIZABLE),
                    id,
                    openSession
            );

            target.saveOrUpdateIsNew(proxy);

            Address address2 = target.get(Address.class, id);

            assertEquals("update on the proxy should work ", proxy.getCity(),
                    address2.getCity());

        } catch (Exception e) {
            e.printStackTrace();
            fail(e.getMessage());
        }

    }

What is the expected output? What do you see instead?
The test should pass.

What version of the product are you using? On what operating system?
trg-dao 0.5.0

I join a patch that corrects the problem.

P.S. : how can we contribute to the code ?
