Henri Yandell commented on STR-3088:
------------------------------------

So the question is whether validwhen should consider a series of whitespace as blank, or if it was intentional to have it not consider whitespace as blank.

> Hello,
> As for validator required/requiredif , the continuous space string (ex. "   ") is jugded blank field.
> But 'null' of validwhen shows only null or length 0 String .
> For ex,'*this* == null' is not hit the continuous space string (ex. "   ").
> I think it should be same behavior because 'Validator Guide' described as follows:
> >  requiredif  - field dependant validator
> >Deprecated, use validwhen.
> Now, requiredif cannot be replaced validwhen.
