I have an array of projected (X,Y)  points, which I am trying to convert to array of (lat,long).  I wrote the following method which will take  a single (X, Y ) and  give me ( Lat, Long). This works. But I do not know how to use this to process my (X,Y) array. This should be simple, but could not get it. function getLatLong(X,Y){         return  (new Promise(function (resolve, reject) {             require(["esri/tasks/GeometryService",                     "esri/geometry/Point",                     "esri/tasks/ProjectParameters",                     "esri/SpatialReference"],                 function (GeometryService, Point, ProjectParameters, SpatialReference) {                     var XCoord = parseInt(X, 10);                     var YCoord = parseInt(Y, 10);                     var inSR = new SpatialReference({wkid: 2274});                     var outSR = new SpatialReference({wkid: 4326});                     var gsvc = new GeometryService("https://mapviewtest.memphistn.gov/arcgis/rest/services/Utilities/Geometry/GeometryServer");                     var inputpoint = new Point(XCoord, YCoord, inSR);                     var prjParams = new ProjectParameters();                     prjParams.geometries = [inputpoint];                     prjParams.outSR = outSR;                      gsvc.project(prjParams);                      gsvc.on("project-complete",function(outputpoint){                         resolve(outputpoint);                     });                     gsvc.on("error",function(err){                         reject(err);                     })                 });         }));//promise     } Thanks Muralidhar Moka ...

We are tying to upload attachments using featureLayer.addAttachment operation. We are using ArcGIS javascript API 3.8 and Emberjs. Note: We do not have a proxy for our ArcGIS server. // The proxy url you see does not work.           is it necessary to use a proxy? Can we do without it. Here is the code file.hbs ======= <div class="form-group"> <div class="col-sm-12 col-md-7 col-lg-7"> <form id="myForm"> <div class="col-sm-8"> <input type="file" name="attachment" /></div> <div class="col-sm-4"> <button class="btn btn-success" type="submit" id="upload" {{action "addAttachments" }}>Submit</button></div> </form> </div> </div> file_controller.js ============ addAttachments:function(){ var controller = this; require([ 'esri/layers/FeatureLayer' ], function ( FeatureLayer ) { esri.config.defaults.io.proxyUrl = "https://mapviewtest.memphistn.gov/proxy/proxy.ashx"; esri.config.defaults.io.alwaysUseProxy = false; var objId = controller.get('projObjectId'); var attchUrl = App.Config.services.pmsPhotoService + objId; var featureLayer = new FeatureLayer(attchUrl); var form = document.getElementById("myForm"); featureLayer.addAttachment(objId, form ,callback , function(err){ console.log(err); }); function callback(result){ console.log(result); } }); }, Here is the log of console with all variables and err message and snap of the same log. our attachment url has no problem.

Hi, Can we start a Python script from a widget on a button Click. Say I will have a button and Textbox for location of the file. I saw an earlier post on this in the community, but there was not satisfactory answer. Note: our python script is reading attributes data and writing excel files  Thanks Muralidhar Moka. ...

cannot render a thematic map, color wont show. Hi trying to create a thematic map for a feature Layer. Here is what I did. I. created a map. 2.Created a basemap layer and added it to the map. 3.created a feature layer and added it to the map. 4.then tried to use the smartMapping.createClassedColorRender  ( I set baseMap like baseMap:map). 5.what I get is I only see the featurelayer boudries with some color. but the featureLayer polygons are not colored. may be in step 4. I did not set my baseMap layer correctly(do not know how to do it). Can any one help me, what my mistake is. I used the following as an example from ArcGIS javascript samples.
