When I'm trying to save BMP as: public void SampleBean.ejbStore() throws EJBException, RemoteException {
|  try {
|   Session hsession = myHelper.getCurrentSession();
|   Session dynamicSession = hsession.getSession(EntityMode.MAP);
|   dynamicSession.update(_objData);
|  } catch (NamingException e) {
|   e.printStackTrace();
|  }
| }

I have a serious issue - SampleBean.ejbStore doesn't save data to DB, and in the same time, Hibernate is sure that all data is stored.
As you can see from stacktrace, Hibernate stores data into internal cache, but doesn't flush this data into DB. IMHO, it happens because the synchronizer isn't created, which in turn happens because another Hibernate synchronizer exists and executes before SampleBean.ejbStore call.

So, is it a software bug or incorrect configuration of my environment?
