Get result from asynchronous geoprocessing task

NeoGeo

I am using this asynchronous geoprocessing task example to rewrite an existing Flex widget to use a geoprocessing service instead of a non-ESRI REST service:
https://developers.arcgis.com/flex/sample-code/asynchronous-geoprocessing.htm

The geoprocessing task submits successfully and according to Fiddler, the service returned the correct data in single output parameter named "myresults" which is a string (containing json data).

At this point, Flex just hangs with a busy cursor apparently in gp_getResultDataCompleteHandler() because everything I have tried using event.parameterValue to get the result from the service has failed. Even just a plain Alert.show with event.parameterValue seems to be ignored.  Can anyone tell me how to get the service result from the parameter and stuff it into an array so that I can then do something like this:

    if (results != null && myresults.records != null)     {      var records:Array = results.records;      buildMyString(records);      var recordsList:ArrayList = new ArrayList(records);      dgResults.dataProvider = recordsList;      showStateResults();     }

This was the URL of the last request : http://<servername>/arcgis/rest/services/Geoprocessing_Services/MyService/GPServer/MyScript/jobs/<jobid>/results/myresults?f=json&returnType=data

The data returned by the service looks like this:
{"paramName":"myresults","dataType":"GPString","value":{"records": [{"layer": "Wolves", "value": "-999"}, {"layer": "Coyotes", "value": "-999"}, {"layer": "Dingos", "value": "5.44373945354"}]}}

The relevant portions of the code are:

  <esri:Geoprocessor id="generateStatsGP"          url="{genURL}"          fault="gp_faultHandler(event)"          getResultDataComplete="gp_getResultDataCompleteHandler(event)"          jobComplete="gp_jobCompleteHandler(event)"          outSpatialReference="{map.spatialReference}"          useAMF="false"/>        var params:Object = {"f":"json", "location":geomJSON, "locationtype":geomType,"units": distanceUnits.toUpperCase()};     generateStatsGP.submitJob(params);     CursorManager.setBusyCursor();       private function gp_getResultDataCompleteHandler(event:GeoprocessorEvent):void    {          Output = event.parameterValue.value;     if (event.parameterValue.paramName == "myresults")     {      //Why doesn't this work?      Alert.show("Yes Virginia, paramName is myresults!");     }     if (event.parameterValue.value != null)     {      //Why doesn't this work?      Alert.show("parameterValue.value is not null");     }      CursorManager.removeBusyCursor();    }          private function gp_jobCompleteHandler(event:GeoprocessorEvent):void    {     if (event.jobInfo.jobStatus == JobInfo.STATUS_SUCCEEDED)     {      generateStatsGP.getResultData(generateStatsGP.submitJobLastResult.jobId, "myresults");     }     else     {      Alert.show(event.jobInfo.jobStatus);      CursorManager.removeBusyCursor();     }    }

Thanks!!

I could not find anything in the ESRI docs past getting the job id, but using the debugger and breakpoints was able to see the object structure and figure it out.  There was still some weirdness that just suddenly disappeared when I started deleting some comments and junk almost like the problems you get when you end up with invisible characters in xml files, so I may never know what exactly caused that, but pretty much the same code worked.  This is what I ended up with to get the data from the parameters:

   private function gp_getResultDataCompleteHandler(event:GeoprocessorEvent):void    {     if (event.parameterValue.value != null && event.parameterValue.value.records !=null)     {      var records:Array = event.parameterValue.value.records;      buildMyString(records);      var recordsList:ArrayList = new ArrayList(records);      dgResults.dataProvider = recordsList;      showStateResults();     }     clearMessage();     CursorManager.removeBusyCursor();    }
