I have tried all kinds of approaches - app group, documents folder - and no luck. I cannot read the json file except from the local bundle.
I've also tried to debug the ActionReuestHandler and that doesn't work either. I tried writing a file out from the request handler and nothing. So it seems like:
a: the handler can't read files other than the one(s) provided in the bundle (this is useless for any kind of dynamic json)
b: the handler has no debugging support at all. so, anything that goes in, can never be seen.
