Data driven style not working in built-in Mapbox GL viewer about t-rex

[pka]

I think, Mapbox GL doesn't offer this functionality You can set a color as function of a field value, but I don't find a way to use the field value as color directly.

[tileset.layer.style]
  type = "line"
  [tileset.layer.style.paint.line-color]
  property = "z_order"
  stops = [{ in = 0, out = "#d8e8c8" }, { in = 3, out = "#cc0000" }]

BTW, when you click on the Maputnik link in the backend, you can experiment with the Mapbox style and translate the generated JSON to TOML afterwards.

Correction: according to https://www.mapbox.com/mapbox-gl-js/example/data-driven-lines/ it could be possible:

[tileset.layer.style]
  type = "line"
  [tileset.layer.style.paint.line-color]
  property = "colour"
  type = "identity"

But when testing with a string field, I always get TypeError: m is undefined

After hitting my for a while, I found out the issue is just in the Mapbox GL viewer within your viewer.js. I updated the viewer to use Mapbox GL JS 0.38, but that still did not fix it. If I use vanilla mapbox 0.38 in a static HTML file pointing to t-rex (like the snippet), I get the expected result.

Huge thanks for your help! :D

Will try to fix that when updating the built-in Mapbox viewer.
