Bonjour,
J'ai une erreur en utilisant Hibernate 3.2.5 que je n'ai pas en utilisant Hibernate 2.0.

Erreur :
"failed to lazily initialize a collection of role: bale2_v4.hibernate.dbmap.Feuille_Fct2.emploisSecondairesFeuilleUtilisateur, no session or session was closed"

Fiche de Mapping :
<class table="TBLE_FCT" name="bale2_v4.hibernate.dbmap.Feuille_Fct2">
<id type="long" name="id" column="KINDEX">
<generator class="increment"/>
</id>
<property type="string" column="LIBELLE" name="libelle" length="150"/>
<property type="string" column="PREFIXE" name="prefixe" length="20"/>
<bag order-by="INDEXSOURCE asc" inverse="true" lazy="true" table="TBLE_USER_FCT2" name="emploisSecondairesFeuilleUtilisateur">
<key column="INDEXCIBLE"/>
<many-to-many class="bale2_v4.hibernate.dbmap.FeuilleUtilisateur" column="INDEXSOURCE"/>
</bag>
</class>

<class table="TBLE_UTILISATEUR" name="bale2_v4.hibernate.dbmap.FeuilleUtilisateur">
<id type="long" name="id" column="KINDEX">
<generator class="increment"/>
</id>
<property type="string" column="KNOM" name="knom" length="140"/>
<property type="string" column="KPRENOM" name="kprenom" length="140"/>
<bag lazy="true" table="TBLE_USER_FCT2" name="emploisSecondaires" order-by="ORDRE asc">
<key column="INDEXSOURCE"/>
<many-to-many class="bale2_v4.hibernate.dbmap.Feuille_Fct2" column="INDEXCIBLE"/>
</bag>
</class>

Il y a 2 tables TBLE_UTILISATEUR, TBLE_FCT linked by a many-to-many association (with a TBLE_USER_FCT2 table).


Le code :
// Save the bean
session.saveOrUpdate(bean); -> Le bean est sauvé

// Je recupere l'objet de TBLE_FCT associee
var utilisateur = bean.getEmploiControleur(); -> Ok, je recupere l'objet

// Maintenant, j'essaye de recuperer l'objet TBLE_UTILISATEUR
var emploiSecondaires = utilisateur.getEmploisSecondairesFeuilleUtilisateur(); -> Error.

Dans tout ce code, la session hibernate est ouverte.

Je pense qu'il y a un problème en navigant via les associations utilisant l'attribut inverse="true",
a moins que ca ne soit dans mes fichiers de mapping?

Quelqu'un peut-il m'aider svp???

Where is the bean loaded? The lazy initialization occurs because the collection has not been initialized in the scope of the session it was loaded with. And, no it has nothing to do with the inverse attribute. You will have force initialization if a bean is going to leave outside the scope of its loading session.


Farzad-

ps. je suis desole je ne peux pas ecrir francais mais je comprend bien.
