But you can pass a component to a different page/component without adding it; like in the example of having a "back link" which wants a page to navigate back to. If you keep that Page in an instance variable in the "back-from" Page you will needlessly serialize that, too, unless you use a PageReference. - Tor Iver --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
