prototype onsubmit not working

[eluser]winterain[/eluser]
ok i've confirmd that it isn't an onsubmit detection problem, apparently clicking on a submit button is different from onchange=this.form.submit();

the detection doesn't work for the latter...

The main problem now is in the ajax.updater code... still troubleshooting.. firebug reports an undefined element upon GetValue(); ...

whatever does that mean... ? hmm
