[OpenLayers-Users] KML layer vector empty

[Jair Santos]

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:
