wicket Ajax ListView WebMarkupContainer AjaxButton

此例子为wicket中在页面中点检索后，在本页面显示出检索结果所用到的控件：

import java.util.ArrayList;
import java.util.List;
import jp.co.infomart.foods.common.admin.page.BasePage;
import org.apache.wicket.ajax.AjaxRequestTarget;
import org.apache.wicket.ajax.markup.html.form.AjaxButton;
import org.apache.wicket.markup.html.WebMarkupContainer;
import org.apache.wicket.markup.html.basic.Label;
import org.apache.wicket.markup.html.form.Form;
import org.apache.wicket.markup.html.list.ListItem;
import org.apache.wicket.markup.html.list.ListView;

/**
*
* @author admin
*/
public class Test_ListView extends BasePage {
        private Form form;
        private static List books = new ArrayList();
        WebMarkupContainer container;

        public Test_ListView(){
            super();
        form = new Form("myForm");
        this.add(form);
        container = new WebMarkupContainer("listViewContainer");
        container.setOutputMarkupId(true);
//
        ListView listView = new ListView("books",books){

            @Override
            protected void populateItem(ListItem item) {
                Test_ListViewModel book = (Test_ListViewModel)item.getModelObject();
                item.add(new Label("id",Integer.toString(book.getId())));
                item.add(new Label("title",book.getTitle()));
                item.add(new Label("author",book.getAuthor()));
            }

        };
        container.add(listView);
        form.add(container);

        AjaxButton ajaxButton = new AjaxButton("ajaxButton") {

            @Override
            protected void onSubmit(AjaxRequestTarget art, Form<?> form) {
                init();
                art.addComponent(container);
            }

            @Override
            protected void onError(AjaxRequestTarget art, Form<?> form) {
                throw new UnsupportedOperationException("Not supported yet.");
            }

        };
         form.add(ajaxButton);
        }

        public void init(){
            books.clear();
         for(int i=1;i<10;i++){
              Test_ListViewModel book = new Test_ListViewModel();
              book.setId(i);
              book.setAuthor("author"+i);
              book.setTitle("title"+i);
              books.add(book);
           }

        }
}
