I created a class library with two business objects (OrderHeader and OrderDetail) so I can reuse in multiple projects. I set the ParentRelationship field on the OrderDetail business object and built the project.My Winform application references the business object library and I have dragged the two business object components onto the form. Now I trying to set the ParentBusinessObject property on the OrderDetail business object and I receive a message 'A parent relationship must first be setup before a parent business object can be selected.'
Am I missing something?
