esri.layers and AMD - urgent

GeorgeSimpson — Wed, 10 Oct 2012 22:43:11 GMT

I know that version 3.2 of the JS API is not totally AMD compliant yet, but the application I am writing is. So far I haven't had many issues except for the use of esri.layers within an AMD module. More specifically, I get

TypeError: Unable to draw graphic (geometry:null, symbol:null): _14 is undefined
http://serverapi.arcgisonline.com/jsapi/arcgis/3.2/js/esri/layers/FeatureLayer.js
Line 19

when trying to create FeatureLayers. What can I do within my module to get the layer constructors to work? I've noticed that these errors go away with 3.3 of the API, but since that version is not yet final there are other features that are broken for now (using stores with FilteringSelect).

define(["dojo/_base/declare", "esri/layers/FeatureLayer", "esri/layers/agstiled", "esri/layers/dynamic" ], function (declare, FeatureLayer, TiledLayer, DynamicLayer) {      return declare([], {         id: null,         agsid: null,         URL: null,         layertype: null,         maplayer: null,         constructor: function (lyr) {             this.id = lyr.Layer_ID;             this.ags_id = lyr.AGS_ID;             this.layertype = lyr.LayerType;              switch (this.layertype) {                 case "featurelayer":                     this.URL = lyr.Service_URL + "/FeatureServer/" + this.agsid;                     this.maplayer = new esri.layers.FeatureLayer(this.URL, {                         mode: esri.layers.FeatureLayer.MODE_ONDEMAND,                         outFields: ["*"]                     });                     break;                 case "tiled":                     this.URL = lyr.Service_URL + "/MapServer" + ((this.agsid) ? ("/" + this.agsid) : (""));                     this.maplayer = new TiledLayer(this.URL);                     break;                 case "dynamic":                     this.URL = lyr.Service_URL + "/MapServer" + ((this.agsid) ? ("/" + this.agsid) : (""));                     this.maplayer = new DynamicLayer(this.URL);                     //this.maplayer = new esri.layers.ArcGISDynamicMapServiceLayer(this.URL);                     break;                 default:                     this.URL = lyr.Service_URL + "/MapServer" + ((this.agsid) ? ("/" + this.agsid) : (""));                     this.maplayer = new DynamicLayer(this.URL);                     //this.maplayer = new esri.layers.ArcGISDynamicMapServiceLayer(this.URL);                     break;             }         }     }); });

I don't see a good reason for doing what you're doing in your class but hey, everybody's got their reasons.

On line 21, you reference agsid when you're building this.URL. This should be ags_id as that's what you use at the top of your constructor.

Here's a working example:

define(["dojo/_base/declare", "esri/layers/FeatureLayer", "esri/layers/agstiled", "esri/layers/dynamic"],  function (declare, FeatureLayer, TiledLayer, DynamicLayer) {    return declare([], {     id: null,     agsid: null,     URL: null,     layertype: null,     maplayer: null,     constructor: function (lyr) {       this.id = lyr.Layer_ID;       this.ags_id = lyr.AGS_ID;       this.layertype = lyr.LayerType;        switch (this.layertype) {       case "featurelayer":         this.URL = lyr.Service_URL + "/FeatureServer/" + this.ags_id; // was previously agsid ... missing underscore         this.maplayer = new esri.layers.FeatureLayer(this.URL, {           mode: esri.layers.FeatureLayer.MODE_ONDEMAND,           outFields: ["*"]         });         break;       case "tiled":         this.URL = lyr.Service_URL + "/MapServer" + ((this.agsid) ? ("/" + this.agsid) : (""));         this.maplayer = new TiledLayer(this.URL);         break;       case "dynamic":         this.URL = lyr.Service_URL + "/MapServer" + ((this.agsid) ? ("/" + this.agsid) : (""));         this.maplayer = new DynamicLayer(this.URL);         //this.maplayer = new esri.layers.ArcGISDynamicMapServiceLayer(this.URL);         break;       default:         this.URL = lyr.Service_URL + "/MapServer" + ((this.agsid) ? ("/" + this.agsid) : (""));         this.maplayer = new DynamicLayer(this.URL);         //this.maplayer = new esri.layers.ArcGISDynamicMapServiceLayer(this.URL);         break;       }     }   }); });

And the page that uses the class:

Gladly... I see you marked your original post as the answer, did you mean to do that?
