many-to-one id=3D"true" is not picked up by hibernate in orm.xml =

---------------------------------------------------------------

                 Key: JPA-1
                 URL: http://opensource.atlassian.com/projects/hibernate/br=
owse/JPA-1
             Project: Java Persistence API
          Issue Type: Bug
            Reporter: Rolf Thunbo


When making a composite key referring to a target entity something like the=
 following ORM XML should be defined:

<?xml version=3D"1.0" encoding=3D"UTF-8"?>
<entity-mappings xmlns=3D"http://java.sun.com/xml/ns/persistence/orm"
    xmlns:xsi=3D"http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation=3D"http://java.sun.com/xml/ns/persistence/orm http:/=
/java.sun.com/xml/ns/persistence/orm_2_0.xsd"
    version=3D"2.0">
    <entity class=3D"Subscription">
        <table name=3D"SUBSCRIPTION"/>
        <id-class class=3D"SubscriptionKey"/>
        <attributes>
            ...
            <many-to-one name=3D"owner" id=3D"true">
                <join-column name=3D"FK_SUBSCRIBER_CVR"/>
            </many-to-one>
        </attributes>
    </entity>
</entity-mappings>

But for some reason the id attribute is not picked up by Hibernate, and the=
refore 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 Hi=
bernate would pick up the id attribute on the many-to-one relation.
