That would be one of the perfect fits for a @SessionState object.
@SessionState(create=true)
private ShoppingCart shoppingCart;
...
You can put all logic needed into this class (like addItem(Item it, int
count) and just display it with a ShoppingCartView component.
For example with a simple Parameter you could discern if it is the small
view , which is mostly in the top right corner of the page which only tells
you the number of items and the sum of their prices or the full blown view
needed in the checkout process or in an overview where the customer can
change the number of items to buy or delete them from the basket etc.You
would only need different blocks for each type in the template and delegate
to them depending on the parameter.
public class ShoppingCartView {
@Parameter(required=true, value="small" defaultPrefix="literal")
private String type;
}
