Thanks for the comprehensive answer. Right now I am testing the
HibernateSessionManager usage.
I added it as the field in my page:
@Inject
private HibernateSessionManager hibernateSessionManager;
and then I commit it in the onFormSubmit method:
public void onFormSubmit(Object observable, Object o) {
Application application = (Application) o;
application.setUser(user);
applicationDao.save(application);
hibernateSessionManager.commit();
publisher.sendApplicationSubmittedMessage(user.getId(),
application.getId());
}
But I feel quite ashamed of this solution. It's like forcing the inner
mechanism of Tapestry's Hibernate Wrapper (or even the Hibernate by itself,
it's flow) to commit the thing before it is appropriate.
However switching from Hibernate to JPA is not an option for me and
Interceptors, if I understand them well, seems like an overhead.
