Hi everybody, i'm going hell for a problem about hibernate and collections.
I have two mapped classes:
public class Indirizzi implements java.io.Serializable {
private int idIndirizzo; (ID)

private DizNazioni dizNazioni;

private String indirizzo;
.................(other code)
}

public class DizNazioni implements java.io.Serializable {

private String siglanazione; (ID)

private String nazione;

private Set<Indirizzi> indirizzis = new HashSet<Indirizzi>(0);
.................(other code)

}

and hbm mapping files:
<hibernate-mapping>
<class name="unibiblio.dati.anagrafica.DAO.Indirizzi" table="indirizzi">
<id name="idIndirizzo" type="int">
<column name="id_indirizzo" />
<generator class="sequence">
<param name="sequence">seq_generica</param>
</generator>
</id>
<many-to-one name="dizNazioni" class="unibiblio.dati.anagrafica.DAO.DizNazioni" fetch="select">
<column name="siglanazione" length="2" not-null="true" />
</many-to-one>
<property name="indirizzo" type="string">
<column name="indirizzo" length="40" />
</property>
</class>
</hibernate-mapping>

and

<hibernate-mapping>
<class name="unibiblio.dati.anagrafica.DAO.DizNazioni" table="diz_nazioni">
<id name="siglanazione" type="string">
<column name="siglanazione" length="2" />
<generator class="assigned" />
</id>
<property name="nazione" type="string">
<column name="nazione" length="50" not-null="true" />
</property>
<set name="indirizzis" inverse="true">
<key>
<column name="siglanazione" length="2" not-null="true" />
</key>
<one-to-many class="unibiblio.dati.anagrafica.DAO.Indirizzi" />
</set>
</class>
</hibernate-mapping>

Well, I'll have a DizNazioni record associated to 1..n indirizzi, and I can associate a DizNazioni to an Indirizzi choosing from lot DizNazioni.
I made a form to insert and modify Indirizzi data:

edit: indirizzo
dropdown: DizNazioni

When I insert it works but if I try to modify it throw error:
identifier of an instance of unibiblio.dati.anagrafica.DAO.DizNazioni was altered from IL to IT

It seems to try to change ID for DizNazioni record instead of change reference in Indirizzi record of it.
How do I have to work? Where's my mistake?

Thanks
Peppe
