Description

The following is a common convention in Tapestry:

<p>
<a href="#" jwcid="clear@DirectLink" listener="listener:doClear">clear counter</a>
</p>

Looking at this, it seems to me that the default for listener could be calculated; that is, capitalize the component id to "Clear" and prefix with "do".

I.e.

getContainer().getListeners().getListener("do" + capitalize(getId()));

Of course, for auto-generated ids, this would be a failure (either no listener found, or something more explicit).
