It is currently possible to submit twice, when the server response is slow. It is better to disable the submit button after submit, to prevent a double submit / improve user experience.
- For all (default) submit buttons in Integrated
- After click submit: disable the submit button and add a spinner animation
- Use the disabled / animation from "Demo 6" on http://jeremypeters.github.io/ng-bs-animated-button/ (skip the text change and the smile)
