For example place order, cashier start new order, add lineitems, end order and make payment. All of these happen seperately, and save button will auto call form.saverecord() to save corresponding view. All relevant Business object will be triggered at that time.

It has been awhile since I have worked with VFP and Mere Mortals (I am working with Mere Mortals.NET mostly now), but I think you may be able to instantiate the Event object on your form, something like:

myForm.oSaleEvent = CREATEOBEJCT("mySaleEvent")

Then in your mySaleEvent code, you could create local references to the business objects on your form. That way, your Event object (myForm.oSaleEvent) is using the business objects already used by the form (Order, OrderDetail). Sorry if that does not make any sense. It has been awhile since I worked with VFP :-).
