Here is the relevant JavaScript part of the code from the working sample modified by Owen Earley You would have to add the URL of the your GP service and input parameter pertaining to your GP service:     require([         "esri/map",         "esri/dijit/Scalebar",         "esri/dijit/Search",         "esri/tasks/query",         "esri/tasks/Geoprocessor",         "esri/tasks/FeatureSet",         "esri/tasks/ParameterValue",         "esri/geometry/Circle",         "esri/graphic",         "esri/geometry/webMercatorUtils",         "esri/symbols/SimpleMarkerSymbol",         "esri/symbols/SimpleLineSymbol",         "esri/symbols/SimpleFillSymbol",         "esri/renderers/SimpleRenderer",         "esri/SpatialReference",         "esri/config",         "dijit/layout/BorderContainer",         "dijit/layout/ContentPane",         "esri/Color",         "dojo/dom",         "dojo/parser",         "dojo/on",         "dojo/dom-style",         "esri/layers/GraphicsLayer",         "dojo/domReady!"],     function (         Map,         Scalebar,         Search,         Query,         Geoprocessor,         FeatureSet,         ParameterValue,         Circle,         Graphic,         webMercatorUtils,         SimpleMarkerSymbol,         SimpleLineSymbol,         SimpleFillSymbol,         SimpleRenderer,         SpatialReference,         esriConfig,         BorderContainer,         ContentPane,         Color,         dom,         parser,         on,         domStyle,         GraphicsLayer) {     // Parse DOM nodes decorated with the data-dojo-type attribute     parser.parse();

Thanks, will do that. ... View more

Hi Owen, I have modified the code in my application and is working now. Could you please delete the link to the URL of my service for the GP task and the source code, and I will paste the required code for others to refer. Thanks ... View more

Thanks, Owen for modifying the code and making it work. I will look at the changes.  ... View more

Owen, I have republished the GP service in WGS84 and I have also set the out spatial reference in the model's environments settings to  WGS 84. I have added the require and function in the application but do not what is the actual code that would be needed I got this from the API reference something like this? require(["esri/geometry/webMercatorUtils"], function(webMercatorUtils) {var pt = Point(0, 0), // a geographic point.     result; if (webMercatorUtils.canProject(pt, map)) {   result = webMercatorUtils.project(pt, map) } }); Here is the updated JS fiddlle, if you could please look at that and let me know if the code looks right? http://jsfiddle.net/1snzLwcm/ I have also updated my attachments to my  original post, with new REST inputs and JSON image Thank you! ...

Owen, Thanks again for the quick response. So you mean that if I publish the service in WGS84 and add this, in GP task input params? like this param.geometries = [webMercatorUtils.webMercatorToGeographic(feature.geometry)]; and  I will not have to worry about, setOutSpatialReference to map's spatial reference? ...

Ionara, I noticed that you have commented out this line in your code, why was that, do we not need this or did you have to republish your GP task again with the map's SpatialReference //gp.outSpatialReference = map.spatialReference, Thanks ... View more

Owen, I thought the adding this to the code while a creating the GP task object should take care of the projection and match the input to the projection of the map : gpTask.setOutSpatialReference = map.spatialReference; Let me know if you think I still need to republish the service with SR 102100. Thanks. ... View more

Hi David, I came across this thread, where DSwingley of ESRI says "Feature Layers don't support a layer's labels. When you create a feature layer from a layer in a map service, you get the geometry and attributes. If you want to label features, look into using a Text Symbol." https://community.esri.com/message/48730#48730 ... View more

Thanks, Robert. It worked! ... View more
