[OpenLayers-Users] KML layer vector empty

Hi all,

I am creating vector layers in format KML. I have the sources in drop box to avoid CORS, but when I load them in the map they have no features. Any ideas about this issue will be very much appreciated.

Thank you 

JJ.

Please see below how I am doing it.

var layers = [ 
 		
	wms_bmid_pipes = new ol.layer.Vector({
				source: new ol.source.Vector({
				url: 'https://dl.dropboxusercontent.com/s/ea4qzzuyk5i2mxt /geid_ws-bmid-pipes.kml?dl=0',
				format: new ol.format.KML() 
				})
			})
            ];
		

Since the layer does not show up in the map I ran the code below to check how many features it has (this code comes from the open layers web site). It turns out that in the console I get "Count after change: 0" , meaning that there are no features.
	
		wms_bmid_pipes.getSource().on('change', function(evt){
			var source = evt.target;
				if (source.getState() === 'ready') {
					var numFeatures = source.getFeatures().length; 
					console.log("Count after change: " + numFeatures);
				}
		});


The point is that the wms_bmid_pipes  contains this:
