[hibernate-issues] [Hibernate-JIRA] Created: (HHH-6204) JoinColumn on non key field fails to populate collection

JoinColumn on non key field fails to populate collection -------------------------------------------------------- Key: HHH-6204 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6204 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 4.0.0.Alpha3, 3.6.4, 4.0.0.Alpha2, 3.6.3, 4.0.0.Alpha1, 3.6.2, 3.6.1, 3.6.0, 3.6.0.CR2, 3.6.0.CR1, 3.6.0.Beta4, 3.6.0.Beta3, 3.6.0.Beta2, 3.6.0.Beta1, 3.3.2 Environment: EAP 5 (hibernate 3.3.2), hibernate 3.6.x, 4.0.x , probably eap4 as well Reporter: Chris Sams Attachments: CompositeKeyExample.zip To duplicate the issue, create three tables in a database with no declared primary or foreign keys. Map entities to two of the tables. One of these entities has a primitive @Id; the other has an @EmbeddedId. Both entities contain an additional field used to join with the third table and populate a collection. This works with the entity that has a primitive @Id but for the entity with @EmbeddedId, trying to do anything with the collection after calling the getter results in: javax.ejb.EJBException: org.hibernate.PropertyAccessException: could not get a field value by reflection getter of jboss.example.DoesNotWorkPk.id1 at org.jboss.ejb3.tx.Ejb3TxPolicy.handleExceptionInOurTx(Ejb3TxPolicy.java:77) .... Caused by: org.hibernate.PropertyAccessException: could not get a field value by reflection getter of jboss.example.DoesNotWorkPk.id1 at org.hibernate.property.DirectPropertyAccessor$DirectGetter.get(DirectPropertyAccessor.java:58) .... Caused by: java.lang.IllegalArgumentException: Can not set java.lang.String field jboss.example.DoesNotWorkPk.id1 to jboss.example.DoesNotWork at sun.reflect.UnsafeFieldAccessorImpl.throwSetIllegalArgumentException(UnsafeFieldAccessorImpl.java:146) I've attached a sample project. The relevant files are Works.java, DoesNotWork.java, and DoesNotWorkPk.java There's also data.sql along with the java files to populate a mysql db, but I think any DB will do. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
