Sure:
package org.miller.wicket.example;
import org.apache.wicket.markup.html.basic.Label;
import org.apache.wicket.markup.html.link.Link;
import org.apache.wicket.markup.html.list.ListItem;
import org.apache.wicket.markup.html.list.ListView;
import org.apache.wicket.model.IModel;
public class Index extends CheesrPage {
public Index() {
add(new ListView<Cheese>("cheeses", getCheeses()) {
private static final long serialVersionUID =
-6160450216067455300L;
@Override
protected void populateItem(ListItem<Cheese> item) {
Cheese cheese = (Cheese)
getDefaultModelObject();
item.add(new Label("name", cheese.getName()));
item.add(new Label("description",
cheese.getDescription()));
item.add(new Label("price", "$" +
cheese.getPrice()));
item.add(new Link<Cheese>("add",
item.getDefaultModel()) {
private static final long
serialVersionUID = 3724016761964076585L;
@Override
public void onClick() {
Cheese selected = (Cheese)
getDefaultModelObject();
getCart().getCheeses().add(selected);
}
});
}
});
}
}
And the CheserPage:
package org.miller.wicket.example;
import java.util.List;
import org.apache.wicket.markup.html.WebPage;
public abstract class CheesrPage extends WebPage {
public CheesrSession getCheesrSession() {
return (CheesrSession) getSession();
}
public Cart getCart() {
return getCheesrSession().getCart();
}
public List<Cheese> getCheeses() {
return CheesrApplication.get().getCheeses();
}
}
