> (attached IntelliJ project with test case that reproduce this issue)
> If I create bidirectional relationship between two dynamic-map entities, commit a transaction and start new session, performing a query to obtain an entity raise LazyInitializationException.
> (full intellij project attached)
> code and mappings:
> public void testSF() throws Exception
> {
> sf.openSession();
> Session es = sf.getCurrentSession();
> Transaction tx = es.beginTransaction();
> Map lolo = new HashMap();
> lolo.put("userName", "lolo");
> es.save("PortalUser", lolo);
> Map dummy = new HashMap();
> dummy.put("name", "dummy");
> es.save("PortalRole", dummy);
> Set roles = new HashSet();
> roles.add(dummy);
> lolo.put("roles",roles);
> Map props = new HashMap();
> props.put("theme", "pp");
> props.put("signature", "alalala");
> lolo.put("dynamic", props);
> es.save("PortalUser", lolo);
> tx.commit();
> sf.openSession();
> es = sf.getCurrentSession();
> tx = es.beginTransaction();
> Query query = es.createQuery("from PortalUser where userName=:userName");
> query.setParameter("userName", "lolo");
>
> //LazyInitializationException on this LINE!!!
> lolo = (Map)query.uniqueResult();

> also note that commenting out this 3 lines makes it work:
> Set roles = new HashSet();
> roles.add(dummy);
> lolo.put("roles",roles);
> So I guess it's about resolving roles relationship during obtaing a user object
