Cast mapovaciho XML vypada takto:
<id name="userPxid" type="int">
<column name="user_pxid" />
<generator class="assigned" />
</id>
Jen podotykam, ze takto mi to vygenerovali Hibernate-tools a jako zacatecnik
jsem nemel duvod neverit.

Mockrat diky za radu, ale zrejme porad něco delam spatne:
Serializable id = session.save(myObject);
session.flush();
return (Integer)id;
i
myObject = (MyObject)session.merge(myObject);
session.flush();
return myObject.getId();
stále vraci 0;

Dobry den,
metoda "save" vraci nove vygenerovany primarni klic. Staci tedy pouzit:
Serializable id = session.save(myObject);
Obsah objektu, ktery je metode predavan jako parametr, se nemeni.
Novy stav si musite nacist sam.
Urcite reseni prinasi metoda "merge", ktera vraci objekt, jenz obsahuje novy
stav (po ulozeni):
Object myObject = session.merge(myObject);
mp.

Ahoj
Zacinam s Hibernate a mam dotaz.
V DB(MySQL5) mam pro ukladani novych zaznamu na primarni klic definovan
auto-increment.
Chci do DB ulozit novy object a hned po ulozeni si vzit prave ten vygenerovany
primarni klic.
V entite je primarni klic typu int.
Entitu ukladam nasledovne:
session.save(myObject);
session.flush();
myObject.getUserPxid();
Problem je, ze mi entita i po ulozeni jako primarni klic stale vraci '0';
Muzete me alespon nakopnout, kde je problem?
