Sorry, this isn't very clear. It might help if you attach a minimal app
that reproduces the problem.
Also, it is not clear why session.sale_order_net is a dictionary with a
single key of 0. It's also not advisable to use an integer as a dictionary
key unless you are doing so for a special purpose. The reason is that when
you see sale_order_net[0], the assumption is that it is a list or tuple
rather than a dictionary.
