Hi,
I'm trying to design a fairly bland EJB application for managing relationships between teachers and students. The skeleton of which is as follows: <<Entity>> Person <<Entity>> Teacher <<Entity>> Student Person doesn't need to be an entity (as it's never instantiated directly), but andromda won't let me generalize a non-entity. Now, as long as I define an explicit <<Identifier>> for the children (TeacherID/StudentID) and not the parent (NO PersonID) everything works as expected. However, if I want to introduce another level into the generalization, such as: <<Entity>> Person <<Entity>> Staff <<Entity>> Teacher <<Entity>> Student to enable the differentiation between a teacher and regular school employee, I run into a problem. If I define StaffID, I receive an XDoclet error (which is the same as if I define a PersonID): Quote: <<Could not find method getStaffId that is supposed to return the PrimKeyField.>> (end of quote) If I don't define a StaffID, I receive the same error, but on the automatically generated ID: Quote: <<Could not find method getId that is supposed to return the PrimKeyField.>> (end of quote) Am I missing something obvious with regard to the generalizations and how I should be modling them? _________________________________________________________ Reply to the post : http://galaxy.andromda.org/forum/viewtopic.php?p=982#982 Posting to http://forum.andromda.org/ is preferred over posting to the mailing list! ------------------------------------------------------- This SF.Net email is sponsored by: NEC IT Guy Games.
