Disabled controls are exempt from validation by design to match how native HTML5 forms work. So it’s expected that async validators wouldn’t run in that case. The bug here is that sync validators are still running. Though it won’t currently affect the calculation of the status, it’s unnecessary and we shouldn’t be calling them at all. I’m working on a PR to ensure sync validators won’t run on disabled controls either.

Hmm, not sure I see why this should be the case. If a control gets disabled a user can’t change its value so in this case validation of the user input doesn’t make much sense, no?

I’m sure I’m missing sth here so if you could elaborate / provide a plunker it would help clarifying.
