[Using an even latest beta]
You'll also get a javascript error:
'ev.preventDefault is not a function'
if your form doesn't use validators.
Anyway, I think both these errors are correct, since the function
is defined as:
postpageFormForm = function(event) {...}
and this in postpageFormForm(this) refers to the
button control, not to an event.
So, you can create an event object and pass it to that function...
or connect the function using dojo
dojo.event.connect(window, "onload", function(e) {
dojo.event.connect(dojo.byId("mySubmitButton"), "onclick", document,
"postpageFormForm");
});
or use something like:
<span jwcid="[EMAIL PROTECTED]:AjaxEventSubmit"
updateComponents="ognl:{'errorMessagePane'}"/>
<input jwcid="@Submit" value="Javascript Submit"
eventListener="onclick=components.onClickSubmit"/>
