------------------------------------
Hi,
another solution (using RefreshEventListener):
import java.util.Map;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.hibernate.HibernateException;
import org.hibernate.event.RefreshEvent;
import org.hibernate.event.def.DefaultRefreshEventListener;
@SuppressWarnings("serial")
public class RefreshListener extends DefaultRefreshEventListener {
private static final Log log = LogFactory.getLog(RefreshListener.class);
@SuppressWarnings("unchecked")
@Override
/**
* This implementation throws no exception, if non-persistent object is refreshed
*/
public void onRefresh(RefreshEvent event, Map refreshedAlready) throws
HibernateException {
if (event.getSession().contains(event.getObject())) super.onRefresh(event,
refreshedAlready);
else log.info("Object " + event.getObject() + " was probably not
persisted yet");
}
}
SessionFactory configuraton (Spring):
<property name="eventListeners">
<map>
<entry key="refresh"><bean class="...RefreshListener"
/></entry>
</map>
</property>
Cascade refresh and new instances
---------------------------------
Key: HHH-1280
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1280
Project: Hibernate Core
Issue Type: Bug
Components: core
Reporter: Gavin King
Attachments: Fix.zip, patch.zip
I have a report that if you have a managed object, with a reference to a new object,
where cascade refresh is enabled, and you refresh the managed object, then you will get an
exception as refresh tries to cascade to the new object. In fact, the new object should
just be ignored.
Looking at the code, this does appear to be the case.
