Hi Roger,

i don´t know if this is related to your problem.
But the json tests in grok return always a dict

class MammothView(grok.JSON):

     def run(self):
         return { 'me': 'grok' }

     def another(self):
         return { 'another': 'grok'}

So maybe you have to say:

    def reverse(self, msg):
       return {'mystring': msg[::-1]}
