Sproutcore

anyone using sproutcore and following the rails 3 example application
DEPRECATED: SproutCore Documentation / Todos 06-Building with Rails 3?
I’ve changed Task to Job because it seems that Task is a reserved word
for rails.
When I run the application I have:

WARN ~ Could not find entry ‘models/job’ required in
todos:source/data_sources/job.js and I see nothing in the web page.
