Wicket, invalidurlexception with ajax panel, possibly ajax calls

["Brown, Berlin [GCG-PFS]" <Be...@Primerica.com>]

I am getting this error intermittently with a web application that uses
ajax calls.  My theory is that on slower Internet connections, parts of
a page aren't returned at the correct time.  With the ajax call, maybe a
user clicks on a link but the link hasn't been entirely processed by the
server back end.
 
Error:
 
org.apache.wicket.protocol.http.request.InvalidUrlException:
org.apache.wicket.WicketRuntimeException: component panel:theLink not
found on page MyHomePage[id = 1], listener interface =
[RequestListenerInterface name=IBehaviorListener, method=public abstract

Version: Wicket1.4.13
 
Pseudo Code:
 
I am using the wicket ajax tabbed panel.  On the panel, there is a link
added to the tabbed panel.  And the tabs are added to the page.  We
normally don't refresh the entire page.  Content is controlled by the
ajax tabbed panel system.
 
It looks like I am getting the invalid URL exception on the link.  I
haven't been able to recreate the error.  It is something that the end
user tends to see.
