Hi Rodrigo,
I'm also implementing message support for our project. We had support
already that wasn't using Opensocial requests, so the work has been
mainly switching to use a MessageHandler and proper request types. One
thing that's currently missing in Shindig is the jsonmessage.js object
for handling requests in the json over rpc case.
I'm working on a basic jsonmessage implementation, mainly to add the
toJsonObject() support since without it the message over the wire
wraps the message fields in a 'fields_':{...} element. Would you like
me to send you what I have once I have it working?
Cheers,
Bobby
