Michael, if you can't get it working with lang.hitch, there is another way you can track scoping inside a class. Here is an example  : define([ //... ], function ( //... ) { var that; return declare(null, { someData: '', postCreate: function () { that = this; that.fetchSomeData().then(that.showData) .otherwise(that.showError); // instead of: // this.fetchSomeData().then(lang.hitch(this, this.showData)) /// .otherwise(lang.hitch(this, this.showError)); }, fetchSomeData: function(){ var deferred = new Deferred(); someAsyncQuery().then(function(response){ that.someData = response; deferred.resolve(response); }).otherwise(function(error){ deferred.reject(error); }); return deferred.promise; }, showData: function(response){ alert(response); }, showError:function(error){ alert(error); } }); });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ I think lang.hitch does the job, but it makes the code really hard to read.  ...

You probably have to instantiate a proper Renderer object. From the docs (FeatureLayer | API Reference | ArcGIS API for JavaScript 3.33 😞 The layer's renderer must be of type SimpleRenderer, ClassBreaksRenderer, or UniqueValueRenderer. Here you have plain object without methods, only properties: featureLayer.renderer = {         "_cache": {     "rotationInfo": null,     "colorInfo": null,     "opacityInfo": null, It probably should be something like this : var renderer = new SimpleRenderer({ ClassBreaksRenderer, or UniqueValueRenderer.     "rotationInfo": null,     "colorInfo": null,     "opacityInfo": null, ... }); featureLayer.setRenderer(renderer); ...

Based on your json output, and knowing it is a ArcGISDynamicMapServiceLayer, the snippet should work if you try: var layerId = 'alallomas_9075';   var operationalLayer = getWebmapOperationalLayerById(layerId); operationalLayer.getLayerObject().then(function(layerObject){    var title = 'Popup title';    var content = 'Custom description. You can use HTML here. <br> And access attribute value like this ${SOME_ATRIBUTE}';     var sublayerId = 0;    if(!layerObject.infotemplates){         layerObject.infotemplates = {};    }     layerObject.infotemplates[sublayerId]= {           infoTemplate: new InfoTemplate(title, content);     }); }) In ArcGISDynamicMapServiceLayer, infotemplates are stored in a different way. The id alallomas_9075_0 means: alallomas is the mapserver name, 9075 is (probably) a random number and 0 is the sublayerId. This is not documented, by the way.... ... View more

For future reference. There is a way, but it doesn't mantain the symbology. You'll have to publish a GPServer to your Arcgis Server to make it happen. It's not possible to do this using only javascript. I've done using arcgis js api 3.x (to create a custom widget for web appbuilder) and a python GPServer. Here is how you can develop it: The python script part: 1. Create a toolbox using Arcmap (or Arcgis Pro, if you're already using it) and publish it as a GPServer. The toolbox must contain a python script using arcpy with the following instructions: 1.2 Toolbox should have 2 input parameters: one for File and the other for the geometry type. 1.3 Toolbox should have 1 output parameter. The output will be a json file to be used in arcgis js api.   1.4 Check input preconditions:       1.4.1 File extension must exist  and must have .dwg extension.       1.4.2 Geometry type must exist and must be polygon, point or polyline. 1.5 Use the arcpy.FeatureClassToShapefile_conversion(pathToTheInputDWGFile, tempDirectory) to convert the DWG file to Shapefile. This is a required step. 1.6 Use arcpy.FeaturesToJSON_conversion(pathToShapeFileInTheTempDirectory, pathToResultJsonFile, "NOT_FORMATTED", "NO_Z_VALUES", "NO_M_VALUES", "NO_GEOJSON") 1.7 Use arcpy.SetParameterAsText(2, pathToResultJsonFile) to send the converted file as json to your arcgis js api. The javascript part: 2. Develop a Widget using Arcgis JS api (3.x or 4.x, it doesn't  matter) with the following inputs: 2.1 - A select box containing the geometry type it is supposed to load from the DWG file: Point, Polyline or Polygon. 2.2 - Input field to add the DWG file. 2.3 - A layer name, to be added to the map. 2.4 - Query the GPServer using esriRequest module and use following code to create a featureLayer from the gpServerJsonResult: For arcgis js api 4.x, you can code something like this: var featureSet = FeatureSet.fromJSON(gpServerJsonResult); var dwgLayer = new FeatureLayer({    title: featureTitle,    id: "aDwgLayer",    source: featureSet.features,    fields: featureSet.fields,    objectIdField: featureSet.fields[0].name,    spatialReference: featureSet.spatialReference,     geometryType: featureSet.geometryType,    renderer: yourCustomRenderer }); map.addLayer(dwgLayer); For arcgis js api 3.x, you can code something like this: var featureCollection = {    layerDefinition: gpServerJsonResult,    featureSet: {       features: gpServerJsonResult.features,       geometryType: gpServerJsonResult.geometryType    } }; var dwgLayer = new FeatureLayer(featureCollection); map.addLayer(dwgLayer); You can find more ways to create the python script to convert CAD data to Arcgis shapefile here: How To: Convert selected CAD data to ArcGIS shapefile, coverage, or geodatabase feature classes using geoprocessing . However, what worked for me was arcpy.FeatureClassToShapefile_conversion tool. ...

A quick and dirty way of doing it, could be something like this: function configurePopupMobileToMaximize (map) {     require(['dojo/aspect'], function(aspect){             aspect.after(map.infoWindow, 'onSelectionChange', function () {                 var feature = map.infoWindow.getSelectedFeature();                 if (feature !== undefined && map.infoWindow._toggleView) {                     map.infoWindow._toggleView();                 }             });     }); } Then just call somewhere this function to configure the behaviour before the user open some popup. configurePopupMobileToMaximize(myMap); Now, this uses a "private" function _toogleView() that we probably shouldn't use directly for some reason. Also, you probably should require the aspect module somewhere else (like a define block) and not inside the function.  But it works. ... View more
