Validators are not called for the compressed value of a MultiValueField.
If, say, I have a MultiValueField subclass which takes a first name and a last name and compresses the two into a "Lastname, Firstname" and this MultiValueField subclass was instantiated using validators = [disallow_john_doe] , one would expect that disallow_john_doe(compressed value) would be executed. However, this is not the case.
Looking at the source, it appears that while the clean() method of django.forms.fields.Field calls run_validators() , the clean() method of django.forms.fields.MultiValueField does not. This is different from expected behaviour and is not documented to my knowledge.
The workaround is to implement validate() in the subclass.
