Just to make sure you haven't overlooked this,
'just_calculated_value' should be of type 'int' in your case (the
option for the select field, not the (option, label) tuple)

The select fields (multiple and single) need a validator if no
options are specified when initialized because it has no way of
guessing one otherwise. I usually don't like this guessing so I
always provide a validator when defining them.
