A possible fix is to check in queryParamsDidChange that the route is actually active. AFAICT the problem happens because it fires (unncessarily?) before the route is actually entered.

This seems the same as an issue I'm trying to trackdown:

https://ember-twiddle.com/0c7e72433e1a3149a7304007fbbd1a54

The issue, as best I can explain it, is that queryParams only transitions have a special short circuit in router.js that fires the queryParamsDidChange https://github.com/tildeio/router.js/blob/master/lib/router/router.js#L38-L43

This code can get hit before the contexts for a route are setup yet, so there is not controller to set the query params on. There must be some code path, maybe setupContexts that gets fired in a normal transition after that short circuit for the queryParams only transition. I spent a few hours digging in the other night to get this far, hoping I can figure it out further over the weekend /CC @rwjblue (this is the crazy shit I wanted to pair w/ you a bit on)

To be clear, the issue appears to not just be for queryParam only transitions. It also happens when you're transitioning to a new route with query params.

This looks to be the same bug as this: #11563.

@raytiley I came to the same conclusion about the controller not being setup yet. Any chance your wip branch can be extended to cover this bug too? I have a branch with the failing tests here

More reproductions of this issues can be found in #13954

@mattmarcum @raytiley @wagenet is this still an issue, perhaps we should close or create a new reproduction of this, what do you think?

[pixelhandler]

Closing for now, feel free to re-open if you can reproduce in the current release of Ember.
