[jboss-user] [EJB 3.0] - Re: RC9 mappedBy and InheritanceType.JOINED problem

[supernovasoftware.com]

GenericItem does not have a @MappedSuperclass.  Adding this gets me past that error, but I then get the error at the bottom of this post and breaks my application in 4.0.4.

Did something change in the EJB3 spec that prevents me from using mappedBy on the property property of a superclass?

The following code appears in my State class.

  |     private Set<Coupling> couplings = new HashSet<Coupling>();
  |     @OneToMany(mappedBy="state")
  |     public Set<Coupling> getCouplings() { return couplings; }
  |     public void setCouplings(Set<Coupling> couplings) { this.couplings = couplings; }

GenericItem has the following and Coupling extends GenericItem


    private State state; 
  |     @ManyToOne
  |     public State getState() { return this.state; }
  |     public void setState(State state) { this.state = state; }

Error
