Right, Hani is sending url form encoded post body, which is not JSON
and will fail to be processed as JSON data.  YUI can be used to
generate your JSON data, please read the documentation at

asyncRequest will not mess up any requests, I've thoroughly used YUI
in conjunction with C::C::REST and it has never let me down (IE6 is a
different story).  As long as you stick to POST and GET, IE6 will be

Also, using Dumper inside of your controller is not recommended,
simply use the $c->log->_dump command.  Additionally, using
$c->req->body is what C::C::REST uses, and after the deserialization
the data will be in $c->req->data and a simple:
  $c->log->_dump( $c->req->data );
shows what exactly is in the request data that has been deserialized for use.
