Hi, I'm switching from Toplink to Hibernate using JPA/EJB3 and Annotations. I'm facing a problem with this change due to the fact that when I try to persist new entities Hibernate throws a "PersistenceObjectException: Detached entity passed to persist". Hibernate expects new entities with ID = NULL and my new entities reach the hibernate layer with ID = 0.
If I were using hibernate xml config files (hbm.xml) I could use "unsaved-value = 0" (for each entity), but I'm using Annotations and there's no "unsaved-value" annotation to use. So, anyone reach this problem? How could I change the default configuration in Hibernate so new entities with ID = 0 will be considered as the default. Or maybe there's a way in FDS2 to configure default value to null? Thanks for any light on this :) C. -- ::| Carlos Rovira ::| http://www.carlosrovira.com ::| http://www.madeinflex.com
