      Domain classes generated by Forge need to override hashCode/equals if they are to be useful in a UI (among other places). This is hard to do if we know nothing about the semantics of the class, but the PersistencePlugin does know something: namely, the Id.

      The following implementation would suffice for my purposes:

      public boolean equals(Object that) {

      if (this == that)

      { return true; }

      if (that == null)

      { return false; }

      if (getClass() != that.getClass()) { return false; }

      if (id != null)

      { return id.equals(((Employer) that).id); }

      return super.equals(that);

      public int hashCode() {

      if (id != null)

      { return id.hashCode(); }

      return super.hashCode();

      But I'm happy for other implementations too.
