receiving json output after validation error
related to : 591696

add pollfield as :
number of default response fields = 2
number of value = unlimited

create new node and leave title empty ,
and add choices to a pollfield using "more coises"
submit with result in validation error about empty node title
after filling it and resubmitting , json output is received

possible to solution is to add #action property to the form , but that is not trivial for node forms
