Hello psamaniego,

If you like to make this form in master-detail relationship you should use RelationType=DetailsCurrentObject and order's detailview (it can be copy of exist view and you can leave only one collection on form).
Use case that presents in DemoApplication can be used only for demonstration one of the representation variant.
Thank you for your patience.

Best regards,
Vitali
