ArcGIS map service layer not loading properly at full extent

Discussion created by bauman312 on Feb 25, 2014
My initial problem was an issue with the layer not loading at all when the page was set to the full extent, despite having changed the Min/Max Scale settings generously when publishing the map service. I corrected this by rectifying the Scale settings in JavaScript:

landBaseLayer.on("load", function() { landBaseLayer.minScale = 0; landBaseLayer.maxScale = 0; }); 

I now have a problem with the layer not loading when entering the page. It loads when I zoom in, and the loaded subset will remain visible when I zoom back out, but everything around it will remain blank. What am I doing wrong? Sorry, I'm totally new to this. I'm using a cached map service, with a Max Record Count of 10,000 (the layer contains just over 7,000 points). The following is the entire code.

   identifyParams = new esri.tasks.IdentifyParameters();
   identifyParams.tolerance = 3;
   identifyParams.returnGeometry = true;
   identifyParams.layerIds = [0];
   identifyParams.layerOption = esri.tasks.IdentifyParameters.LAYER_OPTION_ALL;

   identifyParams.height = map.height;

  function executeIdentifyTask(evt) {
    identifyParams.geometry = evt.mapPoint;
    identifyParams.mapExtent = map.extent;

    var deferred = identifyTask.execute(identifyParams);

    deferred.addCallback(function(response) {

        var feature = result.feature;
        feature.attributes.layerName = result.layerName;
