[jboss-jira] [JBoss JIRA] Commented: (HIBERNATE-73) @OneToOne with @PrimaryKeyJoinColumn does not work right

[David Klotz (JIRA)]

    [ http://jira.jboss.com/jira/browse/HIBERNATE-73?page=comments#action_12411740 ] 
            
David Klotz commented on HIBERNATE-73:
--------------------------------------

This behaviour is clearly NOT expected. The example given in this bug-report (classes Employee and EmployeeInfo "sharing" the same primary key) is taken DIRECTLY from the JPA JavaDoc, see example 2 at: 
http://java.sun.com/javaee/5/docs/api/javax/persistence/OneToOne.html

So @OneToOne and @PrimaryKeyJoinColumn clearly do not work as described in the JPA documentation.

David

> Given the following code:
> @Entity
> public class Employee {
>   @Id Integer id;
>     
>   @OneToOne @PrimaryKeyJoinColumn
>   EmployeeInfo info;
>   ...
> }
> @Entity
>  public class EmployeeInfo {
>    @Id Integer id;
>         ...
> }
> Hibernate creates EMPLOYEE and EMPLOYEEINFO tables, but does not create a foreign key relationship from EMPLOYEEINFO to EMPLOYEE.
> Furthermore, Hibernate does not set the EmployeeInfo's id correctly when persisting it.  The following code:
> EmployeeInfo info = new EmployeeInfo();
> employee.setInfo(info);
> does insert a new row into EMPLOYEEINFO, but it has an id of "1" when it should have an id that is the same as the corresponding Employee.
