I have a class that implements PreInsertEventListener.
The onPreInsert() method is called correctly but when I set properties on the object returned from PreInsertEvent.getObject(), they don't "stick" between the time I modify them and the time the insert is called by hibernate.

Here's my class:
public class AuditPreInsertEventListener implements PreInsertEventListener {

public boolean onPreInsert(PreInsertEvent event) throws HibernateException {
if (event.getEntity() instanceof BaseModel) {
BaseModel model = (BaseModel) event.getEntity();
Date now = new Date();
model.setCreatedDate(now);
model.setModifiedDate(now);
}
return false;
}
}

I looked at the source and API doc for PreInsertEventListener, PreInsertEvent as well as the supplied default implementations but there's no commets or documentation. For example, the onPreInsert() method returns true but there's nothing telling me what that value means. Does it mean, don't do the insert if false but do it if true? I have no idea.

Thanks for any help.

Just came across the same problem myself and found that you need to change that state values in the event for the insert to work. You still need to change your object too in order to avoid an update occuring later when you flush the session.

I'd say you need something like:

you can take a look at http://anshuiitk.blogspot.com/2010/11/h ... event.html. This explains how it works.
