ember.js - Generated Application Controller #needs does not include itself -

i'm migrating web app ember tools ember-cli , having issues. far i've been able handle of errors, not one. have auth controller. on several pages include needs:["auth"], error i'm seeing when restarting server quite odd.

referenceerror: (generated application controller)#needs not  include `auth`. access auth controller (generated application controller), (generated application controller) should have `needs`  property array of controllers has access to. 

i'm not sure error means necessarily, i'm able debug compiled script in firebug, it's not working when try adding needs:whatever auth controller itself.

thanks in advance.
