  | package org.jboss.seam.example.selectitems;
  | 
  | import java.io.Serializable;
  | import java.util.ArrayList;
  | import java.util.List;
  | 
  | import javax.ejb.Remove;
  | 
  | import org.jboss.seam.ScopeType;
  | import org.jboss.seam.annotations.Destroy;
  | import org.jboss.seam.annotations.Factory;
  | import org.jboss.seam.annotations.Name;
  | import org.jboss.seam.annotations.Scope;
  | import org.jboss.seam.annotations.selectitems.SelectItems;
  | 
  | @Name("selector")
  | @Scope(ScopeType.SESSION)
  | public class SelectorAction implements Selector, Serializable
  | {
  |     /**
  |      * 
  |      */
  |     private static final long serialVersionUID = 1L;
  |     private String selected = "Mark";
  |     
  |     public String getSelected()
  |     {
  |         return selected;
  |     }
  |     
  |     public void setSelected(String selected)
  |     {
  |         this.selected = selected;
  |     }
  |     
  |     @SelectItems(valueStrategy=SelectItems.Strategy.STRING)
  |     public List items;
  |     
  |     @Factory("items")
  |     public List getItems()
  |     {
  |         items = new ArrayList();
  |         items.add("Jim");
  |         items.add("Dan");
  |         items.add("Mark");
  |         ArrayList<String> subgroup = new ArrayList<String>();
  |         subgroup.add("Other Developers");
  |         subgroup.add("Steve");
  |         subgroup.add("Ananda");
  |         items.add(subgroup);
  |         return items;
  |     }
  |     
  |     public void select()
  |     {
  |         System.out.println("You selected: "+selected);
  |         if("Dan".equals(selected))
  |         {
  |             System.out.println("Updating selected to Jim");
  |             selected = "Jim";
  |         }
  |     }
  | 
  |     
  |     @Remove @Destroy
  |     public void destroy()
  |     {
  |         // TODO Auto-generated method stub
  |         
  |     }
  | }
  |
