--------------------------------------
Tapestry 4.0 beta 12 - WINXP - Tomcat 5.0.28 - JDK 1.5
This same error occurs with the ExternalService and PageService in the
following conditions:
In the listener method that was invoked from a form post, I call the following
method to redirect to a certain page.
public void redirectAfterPost(IPage page, IRequestCycle cycle)
{
String url = getPageService().getLink(cycle, false,
page.getPageName()).getURL();
throw new RedirectException(url);
}
If the page I redirect to contains a client persisted property, I get the above
error. Same thing happens if you replace "getPageService()" with
"getExternalService()".
Here is the stack trace:

> NullPointerException in PageClientPropertyPersistenceScope when using

> Reporter: Scott Jarvi
> Priority: Minor
>
> A page that's using the 'client' persistence strategy for one of its
> properties includes a ServiceLink that triggers a subclass of RestartService.
> The service logs the user out, invalidates the session and then tries to
> redirect the user back to the 'Home' page, using HomeService.getLink().
> However, trying to get the link from the HomeService resulted in a NPE...

> It seems that the NullPointer is caused by a null IPage in the RequestCycle,

> encoding should be applied.
