I found a nice solution using dojo's ability to listen to an arbitrary
javascript function as if it were a native event.
I attach an empty js function to an arbitrary DOM element like this:
document.getElementById('someDiv').clickRadio=function(radio) {};
and an onclick attribute to my radio buttons:
<span jwcid="@Radio" value="ognl:lv.value" onclick="document.getElementById
('someDiv').clickRadio(this);"/>
Then I can set an EventListener on the server-side
@EventListener(targets = "someDiv", events = "clickRadio", submitForm =
"form")
public void listenToOnclickOnAnyRadioButtonInTheForLoop(IRequestCycle
cycle) throws InterruptedException {
...
}
Works fine.

I'm glad someone else has a need for this as well. From doing a little
bit of research the other day, I found @EventListener annotation that
was introduced into tapestry 4.1+ that "sort of" fixes the problem. I'm
currently using stable release of tapestry 4.0.2, so I didn't bother
going that route. I believe this can be accomplished with tacos, but not
sure. If you find something I would love to see an example, I'll do the
same as well...
Good Luck,
Dennis
