modelformset_factory, initial, and queryset

This is driving me mad, so I must ask the community, in hopes of a workaround: I've got a simple formset of models on a page, generated by modelformset_factory. This particular page will never create forms-- it only modifies existing ones. Therefore the queryset I pass into the formset

Has anybody else experienced a senseless failure of the dev trunk's CSRF verification? Very suddenly this morning, Django won't let me change anything in my admin sites. I didn't update my copy of the SVN trunk, but as soon as I took myself off of the admin-ui branch, it flipped out. Step by

Django is forced to catch your errors, and then bubble them back up to you. If you notice, none of the traceback lines are even in your code-- it's all in Python libs or an Django code. The issue is that you're not seeing raw exceptions, but instead you're seeing reproduced exceptions. I agree
