actually, sorry to bother you, but did you work out something this
simple to support a "submit on enter" for textfields?

Okay, I've got the common problem where I want to prevent some users
from double clicking submit buttons and double submitting a form. I've
got the following script which seems to work except that it seems to
miss one of the clicks. If you double click, it still double submits the
form. If you triple click, however, it double submits like before but
then you get an alert that says 'already submitted 2' meaning that
checkSubmit() has only been called twice. Is there something I'm
missing? Thanks.
<script>
<input-symbol key="form" class="org.apache.tapestry.form.Form"
required="yes" />
<let key="checkSubmit" unique="yes">checkSubmit</let>
<let key="submitted" unique="yes">submitted</let>
<body><![CDATA[
var ${submitted} = false;
var count = 0;
// ensures that the form is only submitted once
function ${checkSubmit}() {
var ret = true;
count++;
if (${submitted} == true) {
alert('already submitted ' + count);
ret = false;
}
${submitted} = true;
return ret;
}
]]></body>
<initialization><![CDATA[
Tapestry.onsubmit('${form.name}', ${checkSubmit});
]]></initialization>
</script>
