JPA: Hibernate extension mixed up OneToOne and OneToMany mappings ----------------------------------------------------------------- Key: JBIDE-11079 URL: https://issues.jboss.org/browse/JBIDE-11079 Project: Tools (JBoss Tools) Issue Type: Bug Components: hibernate Affects Versions: 3.3.0.M5 Reporter: Dmitry Geraskov Assignee: Dmitry Geraskov Priority: Critical Fix For: 3.3.0.Beta1 Attachments: definitions_patch.txt When work with OneToOne or OneToMany mappings there are several problems could occur. One of the is described here: https://community.jboss.org/message/720006 Another I faced myself when tried to repruduce the mapping above: Caused by: java.lang.IllegalArgumentException: invalid mapping key: oneToOne at org.eclipse.jpt.jpa.core.internal.context.java.AbstractJavaPersistentAttribute.getSpecifiedMappingDefinition(AbstractJavaPersistentAttribute.java:325) at org.eclipse.jpt.jpa.core.internal.context.java.AbstractJavaPersistentAttribute.setMappingKey_(AbstractJavaPersistentAttribute.java:216) at org.eclipse.jpt.jpa.core.internal.context.java.AbstractJavaPersistentAttribute.setMappingKey(AbstractJavaPersistentAttribute.java:195) at org.eclipse.jpt.jpa.core.internal.context.java.AbstractJavaPersistentAttribute.setMappingKey(AbstractJavaPersistentAttribute.java:1) at org.eclipse.jpt.jpa.ui.internal.details.PersistentAttributeMapAsComposite$1.morphMapping(PersistentAttributeMapAsComposite.java:82) at org.eclipse.jpt.jpa.ui.internal.details.MapAsComposite.morphMapping(MapAsComposite.java:340) at org.eclipse.jpt.jpa.ui.internal.details.MapAsComposite$3.execute(MapAsComposite.java:206) at org.eclipse.jpt.jpa.ui.internal.details.MapAsComposite$3.execute(MapAsComposite.java:1) at org.eclipse.jpt.common.ui.internal.util.SWTUtil$1.run(SWTUtil.java:138) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:135) ... 23 more To reproduce: 1. Create classes/mappings from issue above 2. Set cursor to PasswordResourceAuditLogEntry#attributes 3. Open JPA Details view FAILURE: "default(basic)" mapping is used 4. Click on the "default(basic)" link 5. Select "OneToOne" from the list FAILURE: Exception The reason is internal hibernate mixed up ManyToOne and OneToOne annotation definitions.
