Hi All,
My question is: I have association mapping of one to many
i.e - teacher (one) and students (many)
the teacher has collection of her students
and the student keep refrerence to its parent (his teacher)


now, my question is how can I have a member/method which will return the teachID in the student class in the GUI side?.

(I need it because when my system is client-server and I marked the parent as transient in the student class because I don't want the the serialized process will bring each time all the object graph but still I want to know the teacher ID of a specific student in the client side).

in the student class I add the following methods


is there a better solution?

[/code]

to me it looks like source of future troubles
someone can call setTeacherID(x) where x!= getTeacher().getID()

can't you do this:
public void setTeacher(Teacher teacher) {
this.teacher = teacher;
this.teacherId = teacher.getId();
}

and make TeacherID property read-only?
