Hi James.
The opensocial.DataRequest.send() method accepts an optional parameter
-- a function object which should be invoked when the response is
received. In your case, _handleData() is executed when viewer
information is available. So place any dependent code in
_handleRequest (or a function that is called from _handleRequest) and
this should work.
Please let me know if this helps or if there's something I missed.
