The current implementation of
BaseFormSet provides a method
_get_empty_form. When a formset is bound, it supplies the data and files it received to the formclass. This results in the formset's empty_form being bound. This can lead to unexpected behaviour, especially when subclassing
The supplied patch has the fix and a test that checks wether the empty_form of a bound formset is still unbound.
Since the empty_form property was added for use as a template, there should be no difference, whatsoever, between the empty_form of a bound and an unbound formset.
