If so, could someone please post some sample code?

 The code fragment I have below doesn't work:

     //friendid defined previously

      var reason = opensocial.newMessage(this.options.message);
      var nav_params = new opensocial.NavigationParameters();
      nav_params.setField(opensocial.NavigationParameters.Field.PARAMETERS, {a:1, b:2});
      nav_params.setField(opensocial.NavigationParameters.Field.OWNER, friendid);
      nav_params.setField(opensocial.NavigationParameters.Field.VIEW, gadgets.views.getCurrentView());
      var params = {};
      params[opensocial.NavigationParameters.DestinationType.RECIPIENT_DESTINATION] = nav_params;
      opensocial.requestShareApp(friendid, reason, null, params);
