> Key: WICKET-3477
> URL: https://issues.apache.org/jira/browse/WICKET-3477
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.5-RC1
> Reporter: Bertrand Guay-Paquet
> Assignee: Martin Grigorov
> Labels: nullpointerexception
> Fix For: 1.4.17, 1.5-RC3

> Attachments: DefaultTimeZone.zip

>
> 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.
