I am developing the JS app using 3.15. I have tried this code in my app Add Shapefile from the esri samples here
Add shapefile | ArcGIS API for JavaScript
but shapefile features added at the same location on map.If the polygon features it shows square but not the actual shape of the polygon.
My map intialextent and Spatialreference for basemap are
var initialExtent = new esri.geometry.Extent({
"xmin": 51.53195000000005,
"ymin": 22.62777042700003,
"xmax": 56.01812603400003,
"ymax": 25.164240001000053,
"spatialReference": {
"wkid": 4326
}
});
map = new Map("map", { extent: esri.geometry.geographicToWebMercator(initialExtent), zoom: 2, logo: false });
map.addLayer(_baseMap);
and code for add shapefile is following and attahced is the screenshot of result all features are at same location.
