inlineformset_factory and max_num

[proft]

Hello!

I have formset with 3 forms max. User filled all forms and save. Then he decided to delete all forms but he can add new form :( because we have

// We're dealing with an inline formset.
// Rather than remove this form from the DOM, we'll mark it as deleted
// and hide it, then let Django handle the deleting:
del.val('on');
row.hide();
forms = $('.' + options.formCssClass).not(':hidden');

JS delete all forms but doesn't allow to add new (because we may add only 3 max forms).

How to be? :)
