So I'm trying to play with the Vector Sample in the API and it doesn't work.
https://developers.arcgis.com/javascript/jssamples/layers_vector.html
I copied the sandbox example to my server.
http://maps.cityoftulsa.org/jsdev/vector/index.html
Then I copied the root.json contents to my own file.
http://maps.cityoftulsa.org/jsdev/vector/style/root.json
I made a single adjustment (background color) to see if my changes would propagate and I get a 404 error.
I know the file is there. I have both copied and renamed it from the server directly. It's there. The contents match exactly with what I am trying to do. Still nothing. I will happily admit I am clueless as to vector styling via JSON, so maybe I'm doing something simple and ignorant of basic concepts. But I can't figure it out.
I even copied and pasted the original JSON back into it and still I get a 404. Confused.
