Hi,
I am implementing OnPreUpdate() and am inserting a new object in there
(for the purpose of a simple commit/rollback system).
When I call Save() on my original entity, I want to intercept, insert
a new copied entity (one without IDs so that it will get INSERTED and
not updated) - and finally, I want the original entity to NOT CHANGE.
I saw the veto functionality based on the return value of the
OnPreUpdate(), but this is saving the original entity and vetoing my
new entity - this is the OPPOSITE of what I want.
Any ideas of how veto the original entity and also insert the new
entity?
Thanks for any ideas/help!
Here is the code:
public class AuditEventListener : IPreUpdateEventListener
{
public bool OnPreUpdate(PreUpdateEvent e)
{
object entity = e.Entity;
Type entityType = e.Entity.GetType();
if (entity is IAuditableEntity)
{
IAuditableEntity auditableEntity =
(IAuditableEntity)entity;
auditableEntity.Audit = new Audit();
Type copyType = typeof(IAuditableCopy<>);
Type[] types = new Type[] { entityType };
Type genericCopyType =
copyType.MakeGenericType(types);
if (genericCopyType.IsInstanceOfType(entity))
{
MethodInfo castMethod =
entityType.GetMethod("AuditableCopy");
object newEntity = castMethod.Invoke(entity, new
object[]{});
using (ISession s =
e.Session.GetSession(EntityMode.Poco))
{
s.Save(newEntity);
s.Flush(); ///////////// NOT GETTING INSERTED
}
}
}
return true; //////// ORIGINAL ENTITY STILL GETS UPDATED
}
}
