Hello,

Could you attach a sample KML file that reproduces the problem? That would help us find out exactly what is causing the bug.

Thanks,

Hannah

Hi,

I modified the KML sample in sandcastle and I was able to reproduce the issue. My code is below, to see the error, click the 'Load KML Network Link' button, then switch to 2D and it should give the stack trace I gave above:

var viewer = new Cesium.Viewer('cesiumContainer');
var options = {
    camera : viewer.scene.camera,
    canvas : viewer.scene.canvas
};

Sandcastle.addToolbarButton('Load KML Network link',
    function() {
        var kmlText='<kml><NetworkLink>' +
            '<name><![CDATA[Test]]></name>' +
            '<refreshVisibility>0</refreshVisibility>' +
            '<flyToView>0</flyToView>' +
            '<Link><href><![CDATA[../../SampleData/kml/facilities/facilities.kml]]></href>' +
            '<viewRefreshMode>onStop</viewRefreshMode>' +
            '<viewRefreshTime>0</viewRefreshTime>' +
            '<viewFormat>BBOX=[bboxWest],[bboxSouth],[bboxEast],[bboxNorth]</viewFormat>' +
            '</Link></NetworkLink></kml>';
        var dom = new DOMParser().parseFromString(kmlText, 'text/xml');
        viewer.camera.flyHome(0);
        viewer.dataSources.add(Cesium.KmlDataSource.load(dom, options));
    });

Sandcastle.reset = function() {
    viewer.dataSources.removeAll();
    viewer.clock.clockRange = Cesium.ClockRange.UNBOUNDED;
    viewer.clock.clockStep = Cesium.ClockStep.SYSTEM_CLOCK;
};

Let me know if you don't see the same. I'm using firefox 43.0.1, FYI...

Thanks,
Rad

Great, thanks Rad! I can confirm this is a bug in Cesium. I've submitted an issue here so we can look into it: https://github.com/AnalyticalGraphicsInc/cesium/issues/3865

Having the code sample was really helpful, thanks for putting that together!

Best,

Hannah
