I reference the bean's interface in order to use it, yes. What's the
alternative? Would I instead access everything through a proxy class and
store the proxy itself into the WebSession, to retain a reference? As it
is, each page in the checkout process changes the Stateful bean's properties
and stores it back into the WebSession. Here is what the Cart page looks
like, in summary:
public class Cart extends BasePage
{
public Cart()
{
//get session - derives from Wicket's WebSession
UserSession session = (UserSession)getSession();
//get cart from session
final ShoppingCartLocal cart = ((UserSession)getSession()).getCart();
//create form
Form form = new Form("cartForm");
//add list of non-bundle Configuration objects to form
form.add(new ListView("orderLinesView", cart.getOrderLines())
{
protected void populateItem(ListItem item)
{
//stuff happens here...
}
}
//...and so on...and so forth...
}
}
