I'm not a Hibernate advanced user, but you're using a XML and Entity class
annotations to configure your Entity?
Anyways... If you want your app to automatically increment your ID before
saving it, you shouldn't use the:
<generator class="assigned" />
That tells hibernate that you want to programatically set the ID.
I guess you should use...
<generator class="identity" />
...instead. Try it out, i guess it will work.

Hello list,
Thanks for all the replies :)
I've actually created the entities and the xml + annotations mappings using the
eclipse hibernate plugin, I've just added the tapestry annotations.
For example for the user entity:
http://dpaste.com/205037/
Hibernate xml mapping file:
http://dpaste.com/205038/
CRUD code:
@Inject
Session session
@Component
private Usuario _user;
@CommitAfter
Object onSuccess()
{
try {
session.persist(_user);
}
catch (RuntimeException e) {
throw e;
}
return this;
}
thank you people!
greetings,
Genis
