Thank you Martin for the excellent explanation.

I did not know setClientInfo() existed which allowed me to create the WebClientInfo instance myself.

Should I put that as "resolved" then?

(for the record, the only information I could find for setting default ClientInfo values was : http://apache-wicket.1842946.n4.nabble.com/Using-ClientProperties-Object-for-User-selectable-Timezone-td1846293.html)

> I want to set a default timezone for client sessions so I added the following line at the end of my CustomSession constructor:
> getClientInfo().getProperties().setTimeZone(TimeZone.getTimeZone("GMT"));
> Doing this coupled with getGatherExtendedBrowserInfo() == true however yields a null pointer exception.
> Some analysis:
> In WebSession#getClientInfo(), there is no clientInfo yet and getGatherExtendedBrowserInfo() is true so a redirect is attempted.
> The line "IRequestHandler activeRequestHandler = requestCycle.getActiveRequestHandler();" produces activeRequestHandler == null.
> Since there is no request handler, the following line "String url = requestCycle.urlFor(activeRequestHandler).toString();" gives a null pointer exception as urlFor returns null.
> If getGatherExtendedBrowserInfo() == false, the default timezone set in the Session constructor works fine.
