[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5405) many-to-one id="true" is not picked up by hibernate in orm.xml

many-to-one id="true" is not picked up by hibernate in orm.xml -------------------------------------------------------------- Key: HHH-5405 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5405 Project: Hibernate Core Issue Type: Bug Components: metamodel Affects Versions: 3.5.2 Reporter: Rolf Thunbo 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.
