IS_IN_DB(..., multiple=True) + checkboxes.widget don't allow zero choice

I have a field with IS_IN_DB(..., multiple=True) validator. If I use default widget (listbox) it allows zero choice (when you don't select anything in the listbox). If I use checkboxes.widget instead it doesn't allow zero choice. As I understand it should allow zero choice no matter what widget I use.

I use version 1.75.5.

It should not allow zero choice since zero (for multiple) is you always have the option to select no option. Perhaps I misunderstood what you ask.

Exactly. The problem is: I do have the option to select no option with the default widget, but I do not have that option with checkboxes.widget. If I don't select any option the validator returns the error "value not in database".

I think this has been fixed some time ago.
