Unable to add machine

I just upgraded to version 1.2.0.1445 and I am unable to add a machine to an environment. I fill in the required information and click “Create” but nothing happens. Hopefully an easy fix

Nevermind. Inspecting the response in firebug showed that there was a validation error that I didnt fill in a thumbprint. Currently this doesn’t show on the screen so it would probably be a good idea to display those errors if something goes wrong.
