The signature of the URL function is URL(a, c, f). If you pass only two
arguments, it assumes they are c and f, and if you pass only one, it
assumes it is f. You passed only 'static/Etichette', so it assumes that is
the function and therefore uses the current application and controller. It
should instead be:
URL('static', 'Etichette', args=[row.etichetta])
'static' is a special value for the controller.
