Hi Jason, glad to hear from you and thank you for the book, great tips there ;-). So the problem is why nhibernate try to update the title table. This is an unidirectional many-one relationship. I just wanna update the table user, i mean the entity user has a reference to the entity title thats clear but in the db the table user has only the fk titleId. Please i need you help and thanks again.
