First concern is that your mock objects got stubbed after it is
returned by new method stub. I alway tend to prepair mock/stub
completely before I use it as argument or any other way.

Second is that tyou try to check that your controller's setup creates
a valid product, but you use mocks, it's up to you to decide whether
your model is valid or not, what it expects to receive and what it
returns. It looks like you get this idea from your models specs where
such a check is useful.

Anyway I feel your problem is that you stub :save! but use :save that
is unexpected.
Could you post your controller code please (create action)?
