Salut,

J'ai fait un fichier de mapping qui décrit un héritage avec la stratégie une table par classe fille avec un discriminant.
A la base ce fichier fonctionne très bien. Le problème que j'ai survient quand dans une des classes filles je veux ajouter une association one to many (dans la classe fille ZoneDataCoordinates)

Voici mon fichier de mapping :

Voici l'erreur que j'ai :

<subclass name="ZoneDataCoordinates" discriminator-value="ZONE_DATA">
        <bag name="coordinatesList" inverse="true" lazy="false" cascade="persist,merge,save-update,delete-orphan">
        		<key column="COORDINATES_ID"/>
        		<one-to-many class="ComplexCoordinates"/>
	    	</bag>
        <join table="ZONEDATA_COORDINATES">
            <key column="COORDINATES_ID"/>
 
        </join>
 
    	</subclass>

Je ne savais pas que l'ordre des balises était important.
