[hibernate-issues] [Hibernate-JIRA] Closed: (HHH-3853) one-to-one mapping doesn support Primary Key Association

one-to-one mapping doesn support Primary Key Association -------------------------------------------------------- Key: HHH-3853 URL: https://hibernate.onjira.com/browse/HHH-3853 Project: Hibernate ORM Issue Type: Bug Components: envers Environment: Hibernate - core 3.4.0-SNAPSHOT, Hibernate - envers (trunk build from today) Reporter: Amar Singh Assignee: Lukasz Antoniak Fix For: 4.1.0 Attachments: hibernate-envers-pkjc.patch, one-to-one-pk.zip one-to-one mapping with primary key association doesn't seem to be working. Eg. Code: <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="org.hibernate.envers.test.integration.onetoone.bidirectional" default-lazy="false"> <class name="BidirectionalRefIngPK" table="BIDIRECTIONAL_REFERENCING_ENTITY"> <id name="id" type="long" column="BIDIRECTIONAL_REFERENCING_ID" > <generator class="foreign"> <param name="property">reference</param> </generator> </id> <property name="data"/> <property column="BIDIRECTIONAL_REFERENCING_ID" generated="never" insert="false" lazy="false" name="id" type="long" update="false"/> <one-to-one name="reference" cascade="save-update" class="BidirectionalRefEdPK" constrained="true" /> </class> <class name="BidirectionalRefEdPK" table="BIDIRECTIONAL_REFERENCED_ENTITY"> <id name="longId" type="long" column="BIDIRECTIONAL_REFERENCED_ID"> <generator class="native"/> </id> <property name="data"/> <one-to-one name="referencing" cascade="all" class="BidirectionalRefIngPK" /> </class> </hibernate-mapping> When we try to load a BidirectionalRefIngPK, the underlying query invokes RelatedAuditExpression and since its not a foreign-key based one-to-one association the loading fails in method addToQuery of RelatedAuditExpression at line 52 (relatedEntity==null) with the following exception: Code: "This criterion can only be used on a property that is a relation to another property." TO REPRODUCE ~~~~~~~~~~~~~ Please find a zip file attached which has four files: - BidirectionalPrimaryAssociation.java (actual testng test case) - BidirectionalRefEdPK.java (Entity 1) - BidirectionalRefIngPK.java (Entity 2) - mappings.hbm.xml Please put the three java files in its package (org.hibernate.envers.test.integration.onetoone.bidirectional) and the mapping file in src/test/resources. Now when you run envers tests you should see the failure. Thanks for this great component !
