Has anyone been able to get TileMill's reference layer plugin to work w/ a TileJSON definition?
In its description, it says it can work either with a mapbox map id or a tileJSON url. I've tried it out successfully with map ids, but when I give it a url to my tileJSON here, nothing loads and the console outputs:
[tilemill] Client Error: Script error.
[tilemill] at :0
[tilemill] Client Error: TypeError: 'undefined' is not an object (evaluating 'a.tiles')
[tilemill] at http://127.0.0.1:20009/assets/tilemill/js/vendor.js:5164
Anyone had any luck with this?
Update: the tileJSON file must be hosted on a server that supports CORS. That solved one problem, but still doesn't work w/ the plugin (same error output).
