[Dariusz Smigiel]

Steps to reproduce:
1. After verification, click "Verify and Deploy"
2. Confirmation popup appears. Confirm and wait for response.

There is a popup with info:
"Danger: There was an error submitting the form. Please try again. "

and traceback in console.

Tested with OSP7 Director Beta2 which uses Tuskar-UI as frontend. This bug doesn't occur any longer.
