I just finished tutorial 14, Configuring a Business Object relationship, and when i got to the end it said "Designing a child form that will show use of a business object relationship is beyond the scope of this tutorial". Well I've looked through the help file and the forums and can't find a parent-child tutorial.



So my question is how do i create a form with two grids on it to demonstrate how this business object relationship works.

The error you're getting when trying to insert the child record is because the Titles business object is configured with PrimaryKeyIsAutoIncremented = True, and the primary key can only be auto-incremented for numeric data types. Since the primary key is not an auto-incremented value, you'll need to set the PrimaryKeyIsAutoIncremented property to False and assign a valid PK value for the new child record before saving. Basically, the server cannot assign the PK value, you'll have to assign it on the client side.
