gp result not getting passed to callback function

JoanSteinbacher

My javascript code is below. The geoprocessing task runs correctly and outputs a Table (not a feature class). Unfortunately the results aren't getting passed to the callback function.

   <script type="text/javascript">
      dojo.require("dijit.layout.BorderContainer");
      dojo.require("dijit.layout.ContentPane");
      dojo.require("dijit.Dialog");
      dojo.require("dojox.grid.DataGrid");
      dojo.require("dojo.data.ItemFileReadStore");

      dojo.require("esri.map");
      dojo.require("esri.tasks.gp");

      //Define global variables here.
      var map;
      var loading;
      var gp;
            
      function init() {
        loading = dojo.byId("loadingImg");
        var initExtent = new esri.geometry.Extent({"xmin":-9215700,"ymin":3216400,"xmax":-9119800,"ymax":3256100,"spatialReference":{"wkid":102100}});
        map = new esri.Map("map",{extent:initExtent});
  
      var imageParameters = new esri.layers.ImageParameters();
        imageParameters.format = "jpeg";  //set the image type to PNG24, note default is PNG8.
      
    //Cached Maps
       //Add the world street map layer to the map. View the ArcGIS Online site for services http://arcgisonline/home/search.html?t=content&f=typekeywords:service    
       var basemap = new esri.layers.ArcGISTiledMapServiceLayer("http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer");
       map.addLayer(basemap); 
       var eluMapServiceLayer = new esri.layers.ArcGISTiledMapServiceLayer("http://gis.tpcmaps.org/ArcGIS/rest/services/LandUse/Existing_Land_Use/MapServer", {"opacity":0.5, "imageParameters":imageParameters});
       map.addLayer(eluMapServiceLayer); 
      var parcelMapServiceLayer = new esri.layers.ArcGISTiledMapServiceLayer("http://gis.tpcmaps.org/ArcGIS/rest/services/Parcels/MapServer", {"opacity":1.0, "imageParameters":imageParameters});
       map.addLayer(parcelMapServiceLayer);
    

      dojo.connect(map, 'onLoad', function(theMap) {
          //resize the map when the browser resizes
          dojo.connect(dijit.byId('map'), 'resize', map,map.resize);
        });
      }
      dojo.addOnLoad(init);
      
      function getLuLc() {
        //Geoprocessing Task 
        gp = new esri.tasks.Geoprocessor("http://gis.tpcmaps.org/ArcGIS/rest/services/ServerTools/GPServer/LuByFolioId");  
      
        console.log("inside getLuLc");
        console.log(dojo.byId("folio").value);
        //var params = { folioID: dojo.byId("folio").value };
        var params = { folioID: "191001.0000" };
        // SHOW LOADING DIALOG
        dijit.byId('loadingDialog').show();
        gp.submitJob(params, completeCallback, statusCallback);
        console.log("after submitJob call");
      }

      function statusCallback(jobInfo) {
        var status = jobInfo.jobStatus;
      }

      function completeCallback(jobInfo){
        console.log("inside completeCallback");
        var status = jobInfo.jobStatus;
        console.log(status);
         if(status === "esriJobFailed"){
           // HIDE LOADING DIALOG
           dijit.byId('loadingDialog').hide();
         }
         else if (status === "esriJobSucceeded"){
           console.log("success, jobId:" + jobInfo.jobId);
           // HIDE LOADING DIALOG
           dijit.byId('loadingDialog').hide();
           console.log("getting data");
          //gp.getResultData(jobInfo.jobId,"Output_Zip_File", downloadFile);
           gp.getResultData(jobInfo.jobId, "OutputTable", displayResult, displayError);
           console.log("after getting result data");
         }
      }

      function displayResult(results, messages) {
         console.log("inside displayResult");
         var resultFeatures = results.features;
         console.log("feature count: " + resultFeatures.length);
      }
      
      function displayError(results, messages) {
          alert("error in getResultData");
      }

The callback function displayResult is getting invoked, but the console gives the error that "resultFeatures" is undefined:

TypeError: resultFeatures is undefined
displayResult(undefined="[object Object]")MySample.html (line 98)
(undefined="[object Array]", undefined=""onGetResultDataComplete"", undefined="displayResult", undefined="[object Object]")?v=3.0 (line 34)
(undefined="[object Object]", undefined="[object Object]", undefined="displayResult", undefined="displayError", undefined="[object Object]")?v=3.0 (line 34)

(undefined="[object Object]", undefined="[object Object]")?v=3.0 (line 34)
(undefined="[object Object]")


Do I have to output a feature class instead of a table for this to work? What am I missing?

Thanks in advance,
Joan

I am having almost the same problem. But with a Feature Class.

The result of my gp task was ok at the server and also runs fine when I call it from the script. The problem is that it is not displayed at my app.

I really cound not find the scritp error. And I spent a week trying to find it.

HELP!

Here is my code:
