What if you have a customer and their orders on the same form? What would thisform.odata.getvalue('CustID') return? Would it return customer.custid or orders.custid?
My point is that I don't think having one oData instance on your form is going to get you very far, and you are going to do a lot of work doing your own data binding. Basically, Microsoft's controls work very well binding themselves to tables, views, and cursors. All of the Microsoft RAD tools push you in the direction of having your middle tier return views that your UI can bind to.
So, to answer you question, the UI would simple bind to a view or REPLACE in a view. Your business object would be responsible for tableupdating the view.
