Thank You.
esri.geometry.xyToLngLat is working.
the app is using esri.layers.ArcGISTiledMapServiceLayer to add several layers.
streetMap, imagery, topoolgies and some others
In some variations I also set the extent.
map.setExtent(new esri.geometry.Extent(-144.1358, 7.9814859, -52.76454, 68.8952, new esri.SpatialReference({wkid: 4326})));
Does the wkid have any effect on xyToLngLat ?
Also set layers does not have a wkid parameter. what does it use ?
Again, thank you
