i think the correct way what would be this:
1) write a mixin that collects the ids of the components in a global
service/aso/whatever
2) after the page has rendered (maybe with a heartbeat or with
in a MarkupRendererFilter service after renderMarkup(...)) use
the collected ids and generate a javascript array
3) add javascript functions to your page that use the javascript array
to register eventhandler for every component id
with prototype you'd do somthing like that
$(element).observe("click",handler);
4) let the registered event handler show the progress bar...
and let the event bubble up!!!
with prototype do NOT call following line:
Event.stop(event);
also take a closer look at PageRenderSupport for javascript
rendering

ps: don't use onClick anymore... instead always register event
handlers; see www.quirksmode.org for more details on events

if you assign that mixing to a submit component, on click the javascript
function
showProgressIndicator is called. the only drawback is, if you do client
side validation and there is
an error, no roundtrip to the server is done and the message stays on
screen :-(
@MixinAfter
public class ProgressIndicator {
@Parameter(value="message:progress-message-label",
defaultPrefix="message")
private String _message;
void beginRender(MarkupWriter writer) {
writer.getElement().attribute("onClick",
"javascript: showProgressIndicator('" + _message + "');");
}
}
