the show address attribute doesnt show for when sale is in a unsaved state. I want my users to see the address and confirm it with a customer before hitting confirm sale/save

True, thats because the edit widget is only one line tall. You could still set a context key, to display on one line mind you. We just do that, and also make the whole address searchable, but then we got 80,000 delivery addresses, no one is searching by name, always by street or GEO.

Works out quite nice because as they type the address the search list narrows and they can see the address to pick.

So you override get_name so that it displays street1+2+city etc, but what if the delivery address and base partner record are the same? How would you see the customer name?

this was similar to my first attempt, except I used one of the on change method: I need it to show while the sale is in a draft so that the user can pick a customer and without saving, have it show the delivery address (to confirm with customer before sale is processed). I think there must be a way of showing this without having to add another field though

Hello,
