I guess I made some assumptions about how submit works instead. So I hacked
this piece of html (wow that felt strange) to see what could work.

<html><head><title>Demo</title></head>
<body>
<form name="Person" action="http://de.selfhtml.org/cgi-bin/formview.pl">
<input type="text" id="lastname" size="30">
<input id="save" type="submit" onclick="dosubmit()" value="Save">
</form>
<script>
function dosubmit() {
  var button = document.getElementById("save");
  var text = document.createElement("span");
  text.innerHTML = "Progress";
  button.parentNode.replaceChild(text, button);
  document.Person.submit();
}
</script>
</body>

This does *not* work. I guess I can't do a submit once I changed dom
structure of the form? So if that's not gonna work it's not gonna work using
Seaside either.

Oh, that works. Maybe because the dom structure of the form hasn't changed
only some attributes?

True. What was I thinking! ;)
I have to admit, that I still feel a bit confused about the jQuery, JS, Ajax
stuff, so I thought setting some attribute "directly" needs to have a
"literal" true.
