Outputting Features in Flex from geoprocess

BryanGunter

Been trying to output features from a geoprocess i am running in flex.  I am new to the flex api so i have been following examples but i seem to be having trouble with the output.  The model i am using works fine in arcgis 10 but i seem to have trouble getting the output from the model to display on the screen. 

This is part of the code i am using:

private function georesult(featureSet:FeatureSet):void
   {
   
    this.cursorManager.setBusyCursor();
   
    if (featureSet.features.length < 2)
    {
     Alert.show("Input not valid")
     return;
    }
   
   
    var sfs_default:SimpleFillSymbol = new SimpleFillSymbol(SimpleFillSymbol.STYLE_SOLID, 0x0000FF, 1.4);
    var N:Number;
    N= 0;
   
   

    for each(var graphic:Graphic in featureSet.features)
    {
    
     N=N+1;
    
    }
   
   
    Alert.show("The number of features input = "+myNumberFormatter.format(N));
   
    var outSR:SpatialReference = new SpatialReference(2254);
    var processSR:SpatialReference = new SpatialReference(2254);
    var params:Object = new Object();
    params.Input = featureSet;
    gp.outSpatialReference = outSR;
    gp.processSpatialReference= processSR;
   
    gp.url = "http://chlorite.ge.olemiss.edu/ArcGIS/rest/services/AGSParkingTools/GPServer/Handicap%20Selection%20Tool";

    gp.submitJob( params) ;
    gp.addEventListener(GeoprocessorEvent.JOB_COMPLETE, executeCompleteHandler);
    gp.addEventListener(FaultEvent.FAULT, faultHandler);
  

   
       
   
   }
   private function executeCompleteHandler(event:GeoprocessorEvent):void          
   {              
   gp.addEventListener(GeoprocessorEvent.GET_RESULT_DATA_COMPLETE, onGetResult);
    gp.getResultData(event.jobInfo.jobId, "Handicap_Selection");


}          
  
   private function onGetResult(event:GeoprocessorEvent):void
   {
    var pv:ParameterValue = event.parameterValue;
    //Alert.show(pv.value.toString());
   
    var fs:FeatureSet = pv.value as FeatureSet;
    if (fs != null)
    {
     var N:Number;
     N=0;
     var myGraphicsLayer:GraphicsLayer = new GraphicsLayer();
     var sfs_default:SimpleFillSymbol = new SimpleFillSymbol(SimpleFillSymbol.STYLE_SOLID, 0x0000FF, 1.4);
    
     for each(var graphic:Graphic in fs.features)
     {
      graphic.symbol = sfs_default;
      myGraphicsLayer.add(graphic);
      myGraphicsLayer.visible=true;
      //map.addLayer(myGraphicsLayer);
      N=N+1;
     }
     Alert.show("The number of features output = "+myNumberFormatter.format(N));
    }
    else
    {
     Alert.show("nothing to return");
    }
    this.cursorManager.removeBusyCursor();
   }

   private function faultHandler(f:FaultEvent):void         
   {              
    this.cursorManager.removeBusyCursor();              
    if (f.type == "fault" && f.fault.name == 'Error' && f.fault.faultCode == '500' && f.fault.faultString == 'Error Executing Task')         
    {                  
     Alert.show("Oops - no results.  Try clicking in an ocean...");            
    }              
    else               
    {                   
     Alert.show("Unexpected fault:\n" + f.toString());            
    }          
   }


at first i thought that perhaps the input was not being sent correctly so i added the alerts and counter to track my inputs and outputs.  Any help would be appreciated. i have included the url to the geoprocess in case anyone can  identify the problem.

Thanks for any help at all,
Bryan

Thank you very much for helping me Dasa.  The line of code you mentioned fixed the problem.

Tyvm,
