Hi there,
I'm using the admin and I have a form admin and an inline admin form. For
this inline admin, I need to ignore modifications done for existing items:
for this task I have done an override of save_existing_objects method for a
Formset which inherit from forms.models.BaseInlineFormset. In this function
I simply call the super with commit=False but doing that cause the
following error:
traceback (most recent call last):

Is there something I'm doing wrong?
