But how are they handling the back button for this?
Form submit -> back button -> Form submit.
This should work i guess, or is this just also then illegal? Then we should make a behahaviour so that you can attach it to a form to make the form block double submits.
I think going back and trying to submit a form should also cause an error. This is why this is not for every form out there.
Take an order form for example, you press order and then go back some time later and press order again...should that go through and end up with another order charged to your card?
I think a behaviour would be the best way to deal with this.
