Download This Working Example of a custom Dojo Widget (dojo41) - unzip into the directory above the location of dojo.js then download test_41.html from this site and view it in a web served browser page.

Your dojo 41 directory structure needs to look like the below.


  yourWebFolder/test_41.html
  yourWebFolder/dojo/dojo.js
  yourWebFolder/acme

See annotations in pages where 41 example was modified to path to match a "typical" - ie non-testing structure.
