KML loading limits in JS API

NathanDorman — Tue, 21 Jul 2015 00:45:32 GMT

The following block of code seems to work fine, but when I code to add a second kml layer, only the second layer loads

This is based off of the kml sample in the js api documentation https://developers.arcgis.com/javascript/jssamples/layers_kml.html

Anyone know why I can only load a single layer? Is there some limits beyond what's stated in the documentation on loading KML layers?

require([

"esri/map", "esri/layers/KMLLayer",

"dojo/parser", "dojo/dom-style",

"dijit/layout/BorderContainer", "dijit/layout/ContentPane", "dojo/domReady!"

], function(

Map, KMLLayer,

parser, domStyle

) {

var map = new Map("map", {

center: [-108.663, 42.68],

zoom: 8,

basemap: "topo",

showAttribution: false,

logo: false

});

parser.parse();

var kmlUrl = "https://dl.dropboxusercontent.com/u/2654618/kml/Wyoming.kml";

var kml = new KMLLayer(kmlUrl);

map.addLayer(kml);

kml.on("load", function() {

domStyle.set("loading", "display", "none");

});

var kml2 = new KMLLayer("https://gmaps-samples.googlecode.com/svn/trunk/ggeoxml/cta.kml");

map.addLayer(kml2);

kml2.on("load", function() {

domStyle.set("loading", "display", "none");

});

Thanks, guess it's something conflicting with my existing web app....

This is working ok for me in the sandbox of the sample you mentioned:
