As I was reading the JBoss RichFaces forum, I saw this post. Here is one possible solution.

   
	
		
		

	
		
	

	
		
	
   


   
	
		Tab 1
	
	
		Tab 2
	
	
		Tab 3
	
	

TestBean.java class:

package test;

import java.util.HashMap;
import javax.annotation.PostConstruct;
import javax.faces.event.ActionEvent;


public class TabsBean {

   private HashMap tabsMap;
   private Boolean value;

   // setters and getters

   @PostConstruct
   public void create (){
	tabsMap = new HashMap ();
	tabsMap.put("tab1", false);
	tabsMap.put("tab2", false);
	tabsMap.put("tab3", false);
   }

   public void disable (ActionEvent event) {
	String id = event.getComponent().getId();
	tabsMap.put(id, value);
   }
   public TabsBean() {}
}

Bean registration in JSF configuration file (manage bean in session scope in order to remember enabled/disabled tab state between requests):

 
  tabsBean
  test.TabsBean
  session
