Key: HHH-2299
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2299
Project: Hibernate3
Type: Bug
Components: core
Versions: 3.2.1
Reporter: Boleslaw Dawidowicz
Attachments: hibernate-issue.tar.gz
(copied from http://jira.jboss.com/jira/browse/HIBERNATE-51)
(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();
assertNotNull(lolo.get("roles"));
assertNotNull(lolo.get("dynamic"));
tx.commit();
}

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
