Does ClearableFileInput work with formsets having empty_permitted set to False?

[wimfeijen]

Hello,

Thanks for creating django-file-resubmit!

I have a question: does file resubmit work with form.empty_permitted is False? I suspect that when I use the ClearableFileInput, it does not check empty_permitted. Also, I can clear required images in a formset. Thanks for checking!

`
class ImageForm(forms.ModelForm):
def init(self, _args, *_kwargs):
super(ImageForm, self).init(_args, *_kwargs)
self.fields['image'].required = False

class Meta:
    model = Image
    fields = ['image', ]
    widgets = {
        'image': AdminResubmitImageWidget,
    }

class MyInlineFormSet(BaseInlineFormSet):
def init(self, _args, *_kwargs):
super(MyInlineFormSet, self).init(_args, *_kwargs)
for form in self.forms:
form.empty_permitted = False
break # only for first form

ImageFormSet = inlineformset_factory(
Room,
Image,
form = ImageForm,
formset = MyInlineFormSet,
extra = 5,
min_num = 1,
max_num = 5,
validate_min = True,
)
