The problem seems to happen because of both PersonCustomer and
LegalEntityCustomer inheriting from Customer, and their primary key being a
foreign key to Customer primary key, when as LegalEntityCustomer is created
its primary key is set to 1 the same of PersonCustomer and that way both
references the first Customer created, the desired behavior should be
create a customer to each PersonCustomer or LegalEntityCustomer, anybody
know how to correct this problem? in the model schema definition?
