Is there a callback listener for "facebook.request"?

Hi you all,

I was wondering if there was a callback listener for “facebook.request”, something like the code below:

local function fbCallbackListener() --do something... end facebook.request( path [, httpMethod, params, fbCallbackListener] )

Yeah, I know that “facebook.request” accepts only “path, http method and params” as parameter.

Anyway, is there a way to do something when a user post on its Facebook wall?

Thank for your help,

have a nice day.
