Hello,
Thanks for the help it got me in the right direction(I think:).

I would love to contribute if it was good enough, not sure how though.

>element.getClientId(), message));
I am not sure what "this.simplify.bindAsEventListener(this)" was for or the
"message" in renderSupport.addScript(String.format(javascript,
element.getClientId(), message));.
I looked into prototype following your lead and came up with:
String javascript = "Event.observe($('%s'),
'click',function(){$('%s').click();});";
renderSupport.addScript(String.format(javascript,
getClientId() + "Button",getClientId()));
And it works like a charm. I don't know if it is the correct way to do it or
not though. It basically puts the observe in the Tapestry.onDOMLoad
function at the bottom of the page.
Thanks,
--James

Very nice! You could even contribute it to the Tapestry components
collection!

AFAIK this is much more of a Javascript issue than a Tapestry one. We
should then use Prototype's event handling.
You could use something like this (not tested):
Component class:
@Inject
private RenderSupport renderSupport;
@BeginRender
void begin(MarkupWriter writer) {
... render HTML without any onclick attributes
// Add a Javascript code line that will bind the click event of your
// button to function
String javascript = "Event.observe($(%s), 'click',
this.simplify.bindAsEventListener(this));";
renderSupport.addScript(String.format(javascript,
element.getClientId(), message));
}
