Error when clicking on entities generated from GeoJsonDataSource

CesiumJS

Hi,

I just recently synced my branch from cesium master branch, and now when I render geojson objects/files and try to click on one of the entities rendered using GeoJsonDataSource, I get the following error: (see attachment as well)

An error occurred while rendering. Rendering has stopped.

Any clues how this can be fixed?

Thanks and Regards,

Since you mentioned you are using master, can you update and try again? There’s a chance that this was fixed yesterday. If it still happens, can you share one of the geojson files causing the problem.

Hi Matthew,

I checked again, but its already up-to-date. I see the same problem on this demo : http://cesiumjs.org/Cesium/Apps/Sandcastle/index.html?src=GeoJSON%20and%20TopoJSON.html&label=undefined.

Here is the geojson file that I am using(see attachment).

Thanks and Regards,

What OS and browser are you using? I can’t reproduce this on Windows with Chrome, Firefox, or IE.

Hi,

I am using ubuntu 14.04. and firefox 28.0. Then I tried it on my google-chrome and it was working fine. So I updated my version of firefox to 36.0.1 and now its working fine. :slight_smile:

Thanks,
