Beginner: findTask does not seem to work

CharlesGeiger

I have combined parts of two sample scripts: query and find.  The query (click a point to highlight the polygon that was clicked in and open an attribute pop-up) works fine.  The find (type a place name in a text box and click an input button to re-symbolize the found point) does not.  I would greatly appreciate another pair of eyes on this.  The map service layers are correct and the fieldnames are correct.  Place names (such as Coatesville or Lancaster) in the attribute table are in title case.  The relevant part of my HTML/JavaScript code is pasted here:

    <script type="text/javascript">
      dojo.require("dijit.layout.BorderContainer");
      dojo.require("dijit.layout.ContentPane");
      dojo.require("esri.map");
      dojo.require("esri.tasks.query");
      dojo.require("esri.tasks.find");

      var map;
      var featureSet, queryTask, query;
      var findPlace, findParams;

      function init() {
          //Map's initial extent:
        var initExtent = new esri.geometry.Extent({"xmin":-8980000,"ymin":4750000,"xmax":-8300000,"ymax":5260000,"spatialReference":{"wkid":102100}});
          //Create the map:
        map = new esri.Map("mapDiv",{extent:initExtent});

          //Creates the shaded relief basemap
        var basemapURL = "http://server.arcgisonline.com/ArcGIS/rest/services/World_Terrain_Base/MapServer";
        var basemap = new esri.layers.ArcGISTiledMapServiceLayer(basemapURL);
        map.addLayer(basemap);

          //Add the landforms layers
        var paMapURL= "https://mapmaker.millersville.edu/ArcGIS/rest/services/PA_Landforms/MapServer";
        var paMap = new esri.layers.ArcGISDynamicMapServiceLayer(paMapURL, {"opacity": 0.4});
        map.addLayer(paMap);

          //Add the places layers
        var paPlacesURL= "https://mapmaker.millersville.edu/ArcGIS/rest/services/PAplaces/MapServer";
        var paPlaces = new esri.layers.ArcGISDynamicMapServiceLayer(paPlacesURL, {"opacity": 0.8});
        map.addLayer(paPlaces);
       
          //Create the find task
        findPlace = new esri.tasks.FindTask(paPlacesURL+"/");
       
          //Create the find paramaters
        findParams = new esri.tasks.FindParameters();
        findParams.returnGeometry = true;
        findParams.layerIDs = [0];
        findParams.searchFields = ["AREANAME"];

          //Listen for Click event:       
        dojo.connect(map, "onClick", doQueryTask);
          //Listen for infoWindow Hide event:
        dojo.connect(map.infoWindow, "onHide", function() {map.graphics.clear();});

          //Build query task:
        queryTask = new esri.tasks.QueryTask (paMapURL+"/2");
       
          //Build query filter:
        query = new esri.tasks.Query();
          query.outSpatialReference = {"wkid":102100};
          query.returnGeometry = true;
          query.outFields = ["PROVINCE", "SECTION"];
      }
     
      function doQueryTask(evt)  {
        map.infoWindow.hide();
        map.graphics.clear();
        featureSet = null;
       
        //onClick event returns the point where the user clicked on the map as "evt":
        query.geometry = evt.mapPoint;
       
        //Executing the task:
        queryTask.execute(query, function(fset) {
          if (fset.features.length === 1) {
            showFeature(fset.features[0],evt);

Nothing jumps out at me...but if your getting features back now it's probably something with your symbol. Try adding graphics using the default symbology options:

graphic.setSymbol(new esri.symbol.SimpleMarkerSymbol());
map.graphics.add(graphic);
