Bidirectional OneToOne mapping with FK and composite PK sharing a column throws MappingException ------------------------------------------------------------------------------------------------ Key: HHH-4939 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4939 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.2 Reporter: Chris Wilson Attachments: HibernateAnnotationMappingOneToOneTest.java A bidirectional one-to-one mapping, where the owning side's column is part of a composite primary key, fails to configure, possibly because OneToOneType#getColumnSpan returns zero instead of the actual number of columns used by the join. When the foreign key column used is not also part of the primary key, or the composite primary key contains only a single column, then the mapping doesn't fail. {code} org.hibernate.MappingException: broken column mapping for: journeyComment.id of: org.wfp.rita.test.hibernate.HibernateAnnotationMappingOneToOneTest$Journey at org.hibernate.persister.entity.AbstractPropertyMapping.initPropertyPaths(AbstractPropertyMapping.java:143) at org.hibernate.persister.entity.AbstractPropertyMapping.initIdentifierPropertyPaths(AbstractPropertyMapping.java:206) at org.hibernate.persister.entity.AbstractPropertyMapping.initPropertyPaths(AbstractPropertyMapping.java:181) at org.hibernate.persister.entity.AbstractEntityPersister.initOrdinaryPropertyPaths(AbstractEntityPersister.java:1725) at org.hibernate.persister.entity.AbstractEntityPersister.initPropertyPaths(AbstractEntityPersister.java:1755) at org.hibernate.persister.entity.AbstractEntityPersister.postConstruct(AbstractEntityPersister.java:2932) at org.hibernate.persister.entity.SingleTableEntityPersister.<init>(SingleTableEntityPersister.java:431) at org.hibernate.persister.PersisterFactory.createClassPersister(PersisterFactory.java:84) at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:267) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1341) at org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:867) at org.wfp.rita.test.base.HibernateTestBase.buildSessionFactory(HibernateTestBase.java:93) at org.wfp.rita.test.base.HibernateTestBase.setUp(HibernateTestBase.java:106) at junit.framework.TestCase.runBare(TestCase.java:128) at junit.framework.TestResult$1.protect(TestResult.java:106) at junit.framework.TestResult.runProtected(TestResult.java:124) at junit.framework.TestResult.run(TestResult.java:109) at junit.framework.TestCase.run(TestCase.java:120) at junit.framework.TestSuite.runTest(TestSuite.java:230) at junit.framework.TestSuite.run(TestSuite.java:225) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:478) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:344) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:196) {code} Test case attached.
