When only a single record is selected, in your sale_order_detail_checkout
function, request.vars.ids will just be a single number (represented as a
string) rather than a list. Because strings are iterable, when you iterate
over the string representation of a multi-digit number, you end up getting
each individual digit. In other words, you code is equivalent to:
for id in '98':
To fix it, you can change your return line to:
return dict(ids = ids if isinstance(ids, list) else [ids])
