Ember.Select not selecting first entry after populating data


I have asked a SO question but I have not received any answers yet.

I have a Ember.Select that starts out empty. Once it has been populated the first item is automatically displayed in the dropdown but it does not always select (binding-wide). It seems to depend upon where the populating happens:

If done in the setupController function of the route then it selects.

For actions it does not.

The only work-around that I have found is to set the selected item yourself after the population has completed.

Am I missing something or is the ‘work-around’ the way to actually handle this when it is not set implicitly?

I have put together a jsFiddle
