> When making a composite key referring to a target entity something like the following ORM XML should be defined:
> <?xml version="1.0" encoding="UTF-8"?>
> <entity-mappings xmlns="http://java.sun.com/xml/ns/persistence/orm"
> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
> xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm http://java.sun.com/xml/ns/persistence/orm_2_0.xsd"
> version="2.0">
> <entity class="Subscription">
> <table name="SUBSCRIPTION"/>
> <id-class class="SubscriptionKey"/>
> <attributes>
> ...
> <many-to-one name="owner" id="true">
> <join-column name="FK_SUBSCRIBER_CVR"/>
> </many-to-one>
> </attributes>
> </entity>
> </entity-mappings>
> But for some reason the id attribute is not picked up by Hibernate, and therefore it does not interpret the relation as a primary key. A workaround is to add a id tag referring to the same property, but it would be nice of Hibernate would pick up the id attribute on the many-to-one relation.
