Hi

This seems to be a popular topic. Already

What struck me today is the inconsistency between @OneToOne(mappedBy) and @OneToMany(mappedBy). With Order and SpecialOrder as in the example above (I'm using SINGLE_TABLE @Inheritance for Order):

@Entity
public class Customer {
  @OneToOne(mappedBy = "customer") // discriminator for SpecialOrder is added to the SQL
  private SpecialOrder specialOrder;
}

@Entity
public class Customer {
  @OneToMany(mappedBy = "customer") // mapping error, "customer" property is no longer available
  private Set<SpecialOrder> specialOrders;
}

Why can I reference parent class property in @OneToOne-mappedBy and have the discriminator added to SQL but I cannot do the same on @OneToMany-mappedBy?
