Hugo,

I've always had good success disabling the submit button alone.  I suppose 
it *might* be possible to change the value of input fields after clicking 
submit and have the changed values communicate to the server (if the typist 
is very quick or the browser is very slow), but I've never had a problem 
with that.

Below is my quickie suggestion (sorry no time to test it).

         oSubmit.onclick = jsSubmitOnce
}

// when button is clicked, disable it before submitting form
function jsSubmitOnce()
{
         this.enabled = false
         this.form.submit()
}
...
<input type="submit" id="SubmitOnce">
