'tuple' object has no attribute 'has_header'

[Margie]

Anyone know what might be causing this error? It occurs when I fill
in one of my forms (ie, from the use interface). I seem to never even
get to the view.py function that processes the POST.

Traceback (most recent call last):
File "/tools/aticad/1.0/external/python-2.5.1/lib/python2.5/site-
packages/django/core/servers/basehttp.py", line 277, in run

AttributeError: 'tuple' object has no attribute 'has_header'

I believe my code is in the same state it was when it was working a
while back. I did some cleanup - removing img and .js files that
weren't in use. I've tried to put all that stuff back, but no luck
and this message isn't very informative ..

Anyway, any hints appreciated.

You're view is returning a tuple insteaed of an HttpResponse object somewhere.
