Bonjour,

Cette situation est bloquante.

Que ce passe-t-il ?
Que faire pour corriger ?

Voici l'Exception rencontrée aléatoirement au moment de la récupération de la collection "executions" d'un objet de la classe Execution.
la librairie JAVA hibernate-core-3.5.6-Final.jar est utilisée.

Caused by: org.hibernate.HibernateException: null index column for collection: mypackage.Execution.executions

Voici le mapping de l'objet Execution:
<class name="mypackage.Execution" table="BN_PVM_EXEC">
<id name="id" column="DBID_">
<generator class="native" />
</id>

[... SKIP ... ]

<list name="executions"
cascade="all-delete-orphan"
inverse="false" fetch="subselect">
<key column="PARENT_" foreign-key="FK_EXEC_PARENT" />
<list-index column="PARENT_IDX_" />
<one-to-many class="mypackage.Execution" />
</list>
<many-to-one name="parent"
class="mypackage.Execution"
column="PARENT_"
foreign-key="FK_INTERN_EXEC_PARENT"
index="IDX_INTERN_EXEC_PARENT" />

[... SKIP ... ]

</class>

Bonjour,

avez-vous pu avancé sur ce sujet ?


cordialement,
