Joseph,
you change is wrong. You did
add(new MyBorder("border")); // Made MyBorder public
// add the clock component
Clock clock = new Clock("clock",
TimeZone.getTimeZone("America/Los_Angeles"));
add(clock);
but you must add the clock to the border like
Border myBorder = new MyBorder("border";
add(myBorder);
Clock clock = new Clock("clock",
TimeZone.getTimeZone("America/Los_Angeles"));
border.add(clock);

Not getting the exception now, but still having a problem.
Just got the latest from Anon CVS and modified ClockPage to
the following below. Now, the update does not happen, no
exception occurs and I can't go back to the page if I click
off of it. Looks like some kind of dead lock or infinite loop.
Thanks
public ClockPage()
{
add(new MyBorder("border")); // Made MyBorder public
// add the clock component
Clock clock = new Clock("clock",
TimeZone.getTimeZone("America/Los_Angeles"));
add(clock);
// add the ajax behavior which will keep updating the
component every 5
// seconds
clock.add(new
AjaxSelfUpdatingTimerBehavior(Duration.seconds(5)));
}
<wicket:extend>
<span wicket:id="border">
This example demonstrates a AjaxSelfUpdatingBehavior.
This behavior can be attached to any component to make it
update itself every x number of milliseconds.
The clock below is updated every five seconds.
<br/><br/>
The server time now is: <span wicket:id="clock">[clock]</span>
</span>
</wicket:extend>
