I couldn't get that to work, but the following did:
(r'^contact/$', login_required(ContactFormWizard([ContactFormPartOne,
ContactFormPartTwo])))
But it complained it couldn't find the __name__ attribute, so I added
the following to my FormWizard subclass:
def __name__(self):
"""When using decorators, Django tries to get the name of the
function
and since we're a class, we'll fail. So add this method to
compensate."""
return 'OrderFormWizard'
I have no idea how if this will create problems for us in the future,
but it does actually work.
