I am using the ArcGIS API for JavaScript 3.32 for the development of widgets in Web AppBuilder.  I have created a locally hosted GeoJson Feature Collection and instantiated it as a FeatureLayer in code (see code snippet below). The issue I am having is that after the FeatureLayer is displayed on my Web AppBuilder map, I an unable to select it using the Select Widget unlike other MapService layers (that are comprised of shapefiles - see screenshot below).  Any information on why this is the case and how to make the FeatureLayer selectable would be helpful. // Add geojon layer code here           require([             "esri/symbols/SimpleFillSymbol","esri/symbols/SimpleLineSymbol",             "esri/geometry/Polygon", "esri/graphic", "esri/Color", "esri/layers/FeatureLayer"           ], lang.hitch(this, function(SimpleFillSymbol, SimpleLineSymbol, Polygon, Graphic, Color, FeatureLayer) {             var sfs = new SimpleFillSymbol(SimpleFillSymbol.STYLE_SOLID,               new SimpleLineSymbol(SimpleLineSymbol.STYLE_DASHDOT,                 new Color([255, 0, 0]), 2), new Color([255, 255, 0, 0.25])             );             // First we create an empty feature collection:             var featureCollection = {               "layerDefinition": null,               "featureSet": {                 "features": [],                 "geometryType": "esriGeometryPolygon"               }             };

Does any one have information on or has created a custom Web AppBuilder Login/Splash Widget that authenticates users (username and password) solely by using Windows Active Directory (not via ArcGIS Online nor via Server/Portal Organization)?  Thanks in advance. ... View more

Looking to confirm that the following malicious python libraries are not present in Runtime Java, QT 100.6 and 100.7.  Specifically, want to ensure the following libraries are not there:  The first is "python3-dateutil," which imitated the popular "dateutil" library. The second is "jeIlyfish" (the first L is an I), which mimicked the "jellyfish" library. If present, what part of the runtime (location) to confirm this? Thanks ... View more

I have a client who wants to build their system as follows: In their system design they want to architect a second ArcGIS Server as a failover?  If so what would the DNS Alias structure look like?  Notice the other "Standby" or failover components.  110 users currently, but hope to expand. I proposed no need for failover: ... View more

ArcGIS Runtime .NET 100.5: I'm reading KML file and displaying the features on a map where the features are crossing the International Date Line and displaying a distortion (gap) going East to West.  I would like to use GeometryEngine.NormalizeCentralMeridian to normalize and eliminate distortion but do not know how to convert KML to geometries in order to apply the normalization.
