Does not work here on v1.8.0.beta9 +21, on this line:

> [@itkin](#):

> ```plaintext
> application.registrations['app-events:main']
> 
> ```

I get this:

```plaintext
TypeError: Cannot read property 'app-events:main' of undefined
    at Object.initialize ((index):482)
    at _ember_jquery-b018f0a….js:14340

    at i.domReady (_ember_jquery-b018f0a….js:13454)
    at p.run (_ember_jquery-b018f0a….js:10544)

```

any idea ?
