Caching problem (bug!?)

Hibernate version: 3.0.5

Hi all,

We have to entities A and B and each instance of A may have multiple instances of B. When we enable caching (EHCache) and delete one of the Bs of an A, and then list all the Bs of A we get the following error:

Code:

org.hibernate.ObjectNotFoundException : No row with the given identifier exists: [com.sun2si.nccin.entities.model.DataTypeParameterInfo#864]

The code used to delete the entity is:

Code:

getHibernateTemplate().delete(entityObject);
getSession().flush();

Could it be related to this bug?

Thanks in advance,
Behi

Thanks,

That helped a lot. BTW I just noticed that the code in question uses a modified version of Spring's OpenSessionInViewFilter:

Code:

public class FlushingSpringSessionInViewFilter extends OpenSessionInViewFilter
{
   protected void closeSession(Session session, SessionFactory sessionFactory) throws CleanupFailureDataAccessException
    {
        if (session != null && session.isOpen() && session.isConnected())
        {
            try
            {
                session.flush();
            }
            catch (HibernateException e)
            {
                throw new CleanupFailureDataAccessException("Failed to flush session before close: " + e.getMessage(), e);
            }
        }

        super.closeSession(session, sessionFactory);
    }
}

Could this also be the reason that the cache behaves the way I mentioned earlier?
