Wrong coordinates showing up on map

MansiShah — Tue, 02 Jan 2018 20:16:01 GMT

I am having trouble getting the correct lat/long coordinates to show up on my map. I have coordinates showing up but they do not reset when they hit 180 or -180. It keeps going on onto 190..191..etc and -182...-190...etc. I keep getting a "Uncaught TypeError: Cannot read property 'clone' of undefined at Object.f. webMercatorToGeographic... Here is code I'm using:

// Create a Map, add the basemapMap to the Map:

var map = new Map({

basemap: basemapMap,

center: [0, 0],

slider: false,

layers: []

});

// Add the Map to the MapView:

var view = new MapView({

....

});

view.on("pointer-move", function(evt){

var coordinates = webMercatorUtils.webMercatorToGeographic(evt.mapPoint);

dom.byId("info").innerHTML = coordinates.x.toFixed(5) + ", " + coordinates.y.toFixed(5);

});

Mansi,

Sounds like you need to normalize the point:

Thank you so much. That worked. I added a point.normalize() underneath the var point = view.toMap(mpx, mpy) and the coordinates are correctly displaying now. Thank you so much.
