Type Parameters:

All Implemented Interfaces:

Serializable, org.apache.wicket.IClusterable, org.apache.wicket.IConverterLocator

public abstract class YuiDDListView<T>
extends org.apache.wicket.markup.html.list.ListView<T>

A ListView with each li bounded to a YuiListDD which will make it reorderable. Note :- the javascript works only with <li>

onAjaxUpdate needs to be called to update the container since AjaxUpdate cannot be called on ListView

 
 Example HTML:
 
                <ul>
                    <li wicket:id="items" >
                        <label wicket:id="item">label</label>
                    </li>
                </ul>
 
 Example Java:
 
                add(new YuiDDListView("items", listData)
                {
                        public void populateItem(final ListItem item)
                        {
                                super.populateItem(item); 
                                item.add(new Label("item", item.getModelObjectAsString()));
                        }
                });
