Hi,
Is property-ref supposed to work with many-to-many?
I tried to use it(I know it is not the best practice but it's a legacy
database), and I get the following exception :
System.Collections.Generic.KeyNotFoundException: La clé donnée était
absente du dictionnaire.
à System.ThrowHelper.ThrowKeyNotFoundException()
à System.Collections.Generic.Dictionary`2.get_Item(TKey key)
à
NHibernate.Persister.Entity.AbstractEntityPersister.GetAppropriateUniqueKeyLoader
(String propertyName, IDictionary`2 enabledFilters)
à
NHibernate.Persister.Entity.AbstractEntityPersister.LoadByUniqueKey
(String propertyName, Object uniqueKey, ISessionImplementor session)
à NHibernate.Type.EntityType.LoadByUniqueKey(String entityName,
String uniqueKeyPropertyName, Object key, ISessionImplementor
session)
I have the following mappings :
<class name="OffreComplete" table="OffreComplete" >
<id name="Id" column="OffreCompleteId" type="Int32" unsaved-
value="null">
<generator class="native"/>
</id>
<set name="Sites" table="OffreCompleteSite" cascade="all-delete-
orphan">
<key column="OffreCompleteId"/>
<many-to-many column="SiteCd" property-ref="Code" class="Site"/>
</set>
</class>
<class name="Site" table="Site" >
<id name="Id" column="SiteId" type="Int32" unsaved-value="null">
<generator class="native"/>
</id>
<property name="Nom" column="Nom" />
<property name="Code" column="SiteCd" unique="true"/>
<property name="Niveau" column="NiveauId" />
</class>
Is it possible to do it at all ?
Thanks for your help.
