Correct. This is no fault of Ember's; it's just a characteristic of the language that I dislike.

Sorry, I was unclear in the post. Building the dashboard took about 3 months. We then add features to it, and maintained it for 5 months after that.

I considered adding breaking that down further; it's definitely more complex than that. The thing is rails "models", "controllers", "routes" are still there in the Ember version. The point is added concepts, structure, files, etc. with Ember.

Hi there. I omitted the hashbang just because I find it ugly.

Loading those other routes first either loads data or modifies the state of the application in a way that is required to display that route

That should be a non-issue as far as I understand, because visiting a nested route causes the parent route code to be executed first. Hence, the confusion.
