I've started from the PosOnLine demo appliance. There with the 'add' and
'sub' buttons you can change the quantity of the products you want to buy,
but there is no total. I've tried to add a total in the view so that when
the the customer 'adds' a product both the quantity and the total changes.
I can't figure out how to correctly fire the total change. There is a
similar thread in this mailing on this subject list but without a useful
conclusion
