undefined local variable or method `configuration' after upgrade to 0.2.0

[thewatts]

Just upgraded ember-cli-rails to 0.2.0, and now when starting my Rails server and hitting http://localhost:3000, I get this:

undefined local variable or method 'configuration' for #<EmberCLI::App:0x007fcfe18fece8>

Cleared out my tmp directory with no avail.

Unsure what could be happening. I had 0.1.* working before upgrading to 0.2.0 - and I tried on a fresh Rails project -- it worked fine.

For some reason, on this existing project, I can't get it to work (even if I start the process over).

[rwz]

Can you provide a stacktrace?

[thewatts]

Yes indeed!

Thanks for the speedy response @rwz!

[thewatts]

@rwz -> Looks like it's blowing up due to me not having a timeout: setting in my app declaration in config/initializers/ember.rb.

Without specifying it, options.fetch is returning configuration.build_timeout
https://github.com/rwz/ember-cli-rails/blob/master/lib/ember-cli/app.rb#L117

Which, configuration doesn't exist in the app instance.

[rwz]

Fixed in 0.2.1 :)

:) Thanks, @rwz !
