[OpenLayers-Users] KML layer vector empty

[Alexandre Dubé]

Hello,

   You should use StackOverflow for questions related to OpenLayers 3: 
http://zeus.dev.where2getit.com/brooksbrothers/index_less_poi.html

   Also, a JSFiddle would be a good way to attract people into helping you.

Regards,

Alexandre
