Mandatory javascript before the submit.

[Sylvain Vieujot]

I have a component that needs to execute a _javascript_ before the forms submit.

I tried to overload the form.submit() in _javascript_, but it doesn't seem to work.
So, I guess I need to add my _javascript_ in the code generated for the form's commandButton s.

Any idea on how to to do that ?

Thanks,

Sylvain.
