Summary: onLoad contributed by Panel is not removed
Initial Comment:
<copied from the wicket-user list:>
please make a bug report for this.
Somehow we need to rebuild the onload (and onunload) of
the body tags completely on ever render
i also bounced into this once but i could go around it
by remembering that i already contributed to it.

In my project, I have a WebPage that is build from
various Panels. During the lifetime of the
user-session, Panels get replaced by others, but the
WebPage is always the same Object.
I now have a Panel that uses a third-party application
(a fat javasript app) which needs to be initialized
when the Panel is loaded, hence I set the onLoad-event
in the Panel markup and the onLoad-event gets appended
to the WebPage's onLoad-event. All nice and well,
but when the Panel is replaced by another, the
onLoad-event is not removed from the WebPage's
onLoad-event. This leads to strange (and very, very
undesirable) effects when the Panel is added to the
WebPage a second time and the Panel's onLoad event gets
appended to the WebPage's onLoad event that still has
the previous onLoad event.
<...>
We need to clear the Panel's onLoad-event contributed
to the WebPage's onLoad-event when the Panel is removed
from the Page.
