Brandon Goodin commented on STS-914:
------------------------------------
It is a matter of consistency. Given the above crude scenario, if I were to
manually select the radio with a value of "" and clicked submit the empty
myRadioValue would be sent along the request. Stripes makes an intentional
decision to interpret the "" myRadioValue request parameter as a null. But, it
does not make an intentional decision to interpret the null as an "" when
displaying the form.
