ok, i see. then i think the value attribute should be validated as 
"required", so IMO a error message should be shown in case it is not set.

other possibillity would be that the viewhelper sets the value property 
for me. i mean the viewhelper knows that i want to bind my model 
property (of type int) to the checkbox value, so i dont see a reason why 
the viewhelper doesnt set the value attritbute according to my models 
property.

or am i wrong?

without knowing much about viewhelpers, i would say, that it's the 
responsibillity of the formViewHelper to render hidden fields where they 
are needed. if you agree, i could dig into this and maybe supply a patch...
