[JSP] Problem update/insert

ianaz · **Posted:** Thu Jun 19, 2008 9:12 am

Hi,
I have a problem when I update something with Hibernate ...
When I update an object in a List sometimes sees the new object, sometimes not, sometimes I see 2changes before... : S
Let me give you an example:

Utente has many Info_utente.

When I update a Info_utente a Utente do:

Code:

Session fac = HibernateUtil.currentSession();
fac.beginTransaction();

Info_utente info_utente = (Info_utente) fac.get(Info_utente.class, id);
  info_utente.setRisposta("test");
Utente utente = info_utente.getUtente();                        
fac.update(info_utente);
fac.update(utente);
fac.flush();
fac.getTransaction().commit(); 

Sorry for my bad english

Hi ianaz,

After looking into ur code, i see you dont update any fields, you just retrieve and persist I'm not sure why you would like to do that...

You dont have to save two times, bring in one-to-one mapping between Utente and Info_utente.. By doing that if you save info_utente, Utente will be saved by hibernate...

ie.

Code:

Session fac = HibernateUtil.currentSession(); 
fac.beginTransaction(); 

Info_utente info_utente = (Info_utente) fac.get(Info_utente.class, id); 
                        
Utente utente = info_utente.getUtente();                        
[color=red][b]utente.setXXX("some value");[/b][/color]
fac.update(info_utente); 
fac.flush(); 
fac.getTransaction().commit(); 

Give us some more info to tackle your issue..

Then I update only Info_utente?
