Nested Routes and Ember Data and Fixtures

Ember Data
1

Am I missing something obvious? Or is there is a bug with Ember Data and the latest router?

Here is the JSBin example:

I cannot figure out why my model is not loading when I navigate to the solution.index route.

Maybe I am missing something basic here. Or maybe I am missing something about how ember can or cannot do nested structures. Any would be appreciated. This has been very frustrating.
