Can't get plugin to work w/ non-MapBox TileJSON file

[jameslaneconkling]

Been trying to get this plugin to work w/ my own TileJSON reference but am getting the following error:

[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

My TileJSON definition is hosted here, which is CORS supported.

I did have luck using the TileJSON url w/ mapbox.js, so I don't think it's an error w/ the definition. And the plugin did work with a MapBox TileJSON url (tried with this). Any thoughts?

Really useful plugin--allows me to style transparent data overlay layers on top of my base layer w/o having to define the whole baselayer w/i the data overlay project. Thanks.

not sure. couple (untested) ideas: 1) maybe another plugin is conflicting - try uninstalling other plugins, or 2) maybe the code in this plugin is not detecting that you are using a custom tilejson url (try adding some print statements to the code like right here to see if that is getting invoked).

I uninstalled all other plugins, but the problem persists.

started digging around in the Map.bones file you suggested. I'm not much of a developer, but familiar enough with js to get much (or some) of what's going on. If I tried to debug where you suggested, what would I use to print messages to the console?

Thanks for the help, of course.

Ah, console.log() seems to work, but only when defined outside of the function assigned to view.prototype.render.

[springmeyer]

console.log() yes, just realize that depending on where it is you might need to check the tilemill console/logs and/or your browsers debug: http://debugbrowser.com/

Did you get it to work? I got the same error.

[jameslaneconkling]

not yet. spent some time trying to debug, but couldn't pinpoint.

(in the meantime, I've just uploaded a small version of the map to mapbox).

I did a workaround (I removed my urls since they are internal)

Ran into something similar using mapbox.js and will record here in case it's of use to anyone. Have a hunch that the problem here is w/ retina displays:

• L.mapbox.tileLayer(layerJSON) appends @2x to tile urls automatically, which obviously won't work w/ tileservers not configured to generate 2x tiles.
• here's a js fiddle recreating the problem w/ mapbox.js.

@pakore 's workaround to hardcode the tile url templates is a good fix. Thanks.

don't have access to a non-retina display at the moment, so can't fully verify. will post when I do.
