[Seaside] callbacks of disabled submit buttons

[Sebastian Sastre]

Ok, here I go.. 

for the record:
f* buttons won't work as supossed with readonly. Is nothing to do with Seaside.
They should, but they won't. Don't ask why.

So.. a way I've found to (almost) achieve this feature (without using ajax) is
to let the button enabled and observe the submit event. If the submit event was
already received (you need to store that state at DOM) then react stopping it to
prevent the extra POST's.
peace & love
