"Don’t call us, we’ll call you". Take a look at the following diagram illustrating an application flow with some calls. We avoid three calls through the Hollywood-Principle and we just have to instanciate the models and data have a clearly defined 296 lifecycle that reflects the corresponding the page flow. Listing 14: public class MyPage extends WebPage { IModel myDataModel; public this approach is that the data gets automatically cleaned up when a user completes or exits the page flow. No manual cleanup anymore! This is basically an automatic garbage collector for your session. 25
