Use route result as input to geoprocessing service?

[BrandonFlessner]

I am trying to pass the output of a route task into a geoprocessing service. I believe I need to take the route result (event.routeSolveResult.routeResults[0]) and (maybe/possibly) convert that to a feature set, then pass the feature set to the geoprocessing service as a parameter. How can this be accomplished?

Or is there a way to convert the graphic layer returned from the route task into a feature set, and pass this to the geoprocessing service?

I have tried to create an array collection from the graphic layer returned from the route task (code below) and I have tried to pass event.routeSolveResult.routeResult[0] to locatorParams.Route (not shown). All efforts have yielded an HTTP Request Error [IOError].

Thanks for any help you can provide!

private function barricadelocator():void

  { 

  var arrColl:ArrayCollection = new ArrayCollection();

  for(var i:int = 0; i<graphicsLayer_Route.numGraphics; i++)

  {

  var gra:Graphic = graphicsLayer_Route.graphicProvider;

  arrColl.addItem(gra);

  }

  var locatorFS:FeatureSet = new FeatureSet();

  locatorFS.features = arrColl.source;

  locatorFS.geometryType = Geometry.POLYLINE;

  locatorFS.spatialReference = new SpatialReference(4269);

  var locatorParams:Object = new Object();

  locatorParams.Route = locatorFS;

  locator.disableClientCaching = true;

  locator.outSpatialReference = map.spatialReference;

  locator.useAMF = false;               

  locator.addEventListener(GeoprocessorEvent.EXECUTE_COMPLETE, locatorCompleteHandler,false,0,true);

  locator.addEventListener(FaultEvent.FAULT, barricadefaultHandler,false,0,true);           

  locator.submitJob(locatorParams);

  //locator.execute(locatorParams);

  }
