Can anyone give pointer on the below mentioned scenario

1> I have Employee and Orders Table
2> EmployeeID is foreign key in Orders Table
3> I m creating Employee and at the same time Adding orders related to that.
4> I dont want to save first the employee object and then the orders object , i want to save all this as one single object.
5> I m getting the exception that can not insert null values for EmployeeId in Orders table.
6> I know that first i can save into Employee table and then into Orders table but i dont want to do that for some reason.

Can anybody throw some light on this issue.

need to see your mapping files for the employee and orders entities. you should be able to map Employee.Orders as and call save session.Save(MyEmployeeObject) and get what you want.

If the <key> column of a <one-to-many> association is declared NOT NULL, NHibernate may cause constraint violations when it creates or updates the association. To prevent this problem, you must use a bidirectional association with the many valued end (the set or bag) marked as inverse="true". See the discussion of bidirectional associations later in this chapter.
