@nickschot is this the same error you were seeing? My initial check was just to move it out of a

TypeError: (0 , _emberMetal.get)(...).getURL is not a function

If so, we might have to chalk this up as one other case where Relay has gone wrong for us.

Ref #315

That is the error that's thrown in the failing test (#314) indeed. See: https://travis-ci.org/poteto/ember-changeset/jobs/426214417#L607

I do not see this error in my ember-bootstrap form (w/ changeset 1.5.0 & ember-model-select). Could be that it's caught somewhere.

I think you also lost some text, what's that second sentence?
