Note, the problem is not with the validator -- if you pass it the value False, it will successfully validate. The issue is that when a checkbox is not checked, the browser sends nothing back for that form field (it does not send back a value of False), so the value passed to the validator ends up being None rather than False.
In your case, just change your code slightly so the validator doesn't get assigned in the case of boolean fields. Assuming you have the field type stored somehow: if is_required and type != 'boolean': Or better yet, just set is_required to False for boolean fields.
