Comment 10 for bug 438671

If I understand correctly, it would be desirable to add client side validation of the form before submitting to Launchpad. This would be quite easy to implement using the concept of properties already available in Checkbox. I have pushed a preliminary branch for your review to make sure that the field requirements are set properly, it seems that only field.live_cd is optional. Let me know what you think and whether this fix should be adequate to close this bug.
