Comment (by codingjoe):
Sorry, I think I fixed the example.
Let me try to be a little more specific to what's wrong:
There are two ways to pre fill a ModelFormSet, by passing a queryset or
initial data. The later is described here:
https://docs.djangoproject.com/en/dev/topics/forms/formsets/#using-
initial-data-with-a-formset
Sadly a ModelFormSet only takes `queryset` in account for
`initial_form_count`
https://github.com/django/django/blob/master/django/forms/models.py#L579
Therefore initial data is used for form construction but not accounted for
form saving, which is very much unexpected.
