Caching

[Lennart Benoot <lb...@axelera.net>]

Hey Folks,

When setting the vm property: -Dnet.sf.tapestry.disable-caching=true
The login mechanism of my web application failed. The login mechanism is 
implemented with the tapestry VLib application as an example. An AdminPage 
checks wether a user is logged in. If he isn't, a PageRedirectException is 
thrown:

Login lPage = (Login) cycle.getPage( IConstants.PAGE_LOGIN);
lPage.setCallback(new PageCallback(this));
		
throw new PageRedirectException( lPage);

later, when logging in,  it seems that the PageCallback that should be 
available in the LoginPage is null.

Any solutions to this problem?

Regards,
Lennart

Did you make the callBack property of your Login page persistent?  In 2.3,
this means invoking fireObservedChange() from the accessor method.  In 2.4
you would probably declare the property in the page spec and let Tapestry do
the rest.
