[hibernate] Violation de contrainte unique

Bonjour,

Je suis nouveau sur ce forum et débute en hibernate. Je ne comprends pas pourquoi lors d'une requete de lecture (récupération d'une personne et de ses associations avec les immeubles dans lesquels elle est) j'ai une erreur à cause d'une violation de contrainte (et donc d'une tentative d'insertion dans la base) ; pouvez vous m'expliquer pourquoi lors d'un "select" j'ai cette exception dûe à un "insert" ?
Mon mapping est - il erroné ? Y'a-t-il quelquechose à indiquer pour éviter cet insert ?

Merci d'avance pour votre aide.

(à savoir que les traces que j'ai mises indiquent que les immeubles sont bien récupérés, mais c'est après la récupération, lors du "commit" que l'exception apparait)

Hibernate version: 3

Mapping de ma personne pour l'association vers les building :

<set name="listPersonBuilding" table="T_PRSBUILD_EA4">
<key column="PBU_FK_ID_PER" not-null="true"/>
<composite-element class="com.sgcib.pops.business.model.person.PersonBuilding">
<property name="officeName" column="PBU_VA_OFFICENAME" type="java.lang.String" length="50" />
<property name="floor" column="PBU_VA_FLOOR" type="java.lang.String" length="20" />
<property name="picture" column="PBU_VA_OFFICEPICTURE" type="java.lang.String" length="50" />
<property name="active" type="java.lang.Boolean" column="PBU_BL_ACTIVE" />
<property name="phone" column="PBU_VA_PHONE" type="java.lang.String" length="20" />
<property name="cell" column="PBU_VA_CELL" type="java.lang.String" length="20" />
<property name="fax" column="PBU_VA_FAX" type="java.lang.String" length="20" />
<property name="principal" type="java.lang.Boolean" column="PBU_BL_PRINCIPAL" />
<many-to-one name="building" column="PBU_FK_ID_BUI" />
</composite-element>
</set>


Code de ma requete de lecture :

Criteria lCriteria;
Object lResult;
try
{
lCriteria = getSession(true).createCriteria(pObjectClass);
if (pObjectClass.getName().equals("Person"))
{
lCriteria.setFetchMode("listPersonActivity", FetchMode.JOIN);
lCriteria.setFetchMode("listBuildings", FetchMode.JOIN);
}
lCriteria.add(Restrictions.idEq(pPk));
if (lCriteria.list().size() <= 0)
{
throw new FinderException("Item with identifier :" + pPk + " not found.");
}
lResult = lCriteria.list().get(0);
} catch (Throwable lThrowable)
{
sLogger.error("Problem during query execution : " + lThrowable.getMessage());
throw new TechnicalException(lThrowable);
}
return lResult;

Name and version of the database you are using: Oracle 10 g

Quelques traces de plus (showsql = true) :
on voit bien qu'apres le select, au moment du commit il cherche à faire un delete puis deux insert ... mais je ne vois pas pourquoi.

Merci d'avance.
