I'd propose an alternative way of doing the same thing: 6748d37

Calling the "success" action explicitly outside of the loader feels like a hack. It's best to just use the power reducers give us and have the results reducer (via the loader) directly change itself when a tab is changed.

I'm approving the PR. Feel free to merge if you agree with the change.

That's great, thanks!
