I found a workaround, but it's not pretty. The solution is to override
the _perform_call() method of DecoratedController in your controller:
def _perform_call(self, controller, params, remainder=None):
# If not a decorated method just call it (needed for
__before__ and __after__)
if not hasattr(controller, 'decoration'):
if remainder is None:
remainder = []
return controller(*remainder, **dict(params))
return DecoratedController._perform_call(self, controller,
params, remainder)
