Problemas com escope session

Olá a todos,
Esou criando uma aplicaçao com myfaces e tomahawlk e necessito configurar meu
manager-bean de uma classe com escopo 'session’conforme o exemplo abaixo:

Fonte da Classe:

package com.asgard.framework.action;

import java.util.ArrayList;
import java.util.List;

import com.asgard.framework.util.LogClass;
import com.asgard.framework.util.Message;

public class TesteAction &#123;
	public String nome;
	
	public List&lt;Message&gt; listaTeste;
	
	public TesteAction&#40;&#41; &#123;
		 this.listaTeste = new ArrayList&lt;Message&gt;&#40;&#41;;
		 
		 this.listaTeste.add&#40;new Message&#40;"Teste 01", 1&#41;&#41;;
		 this.listaTeste.add&#40;new Message&#40;"Teste 02", 1&#41;&#41;;
		 this.listaTeste.add&#40;new Message&#40;"Teste 03", 1&#41;&#41;;
		 this.listaTeste.add&#40;new Message&#40;"Teste 04", 1&#41;&#41;;
		 this.listaTeste.add&#40;new Message&#40;"Teste 05", 1&#41;&#41;;
		 LogClass.log&#40;this, "create"&#41;;
	&#125;
	
	public List&lt;Message&gt; getListaTeste&#40;&#41; &#123;
		LogClass.log&#40;this, "getListaTeste"&#41;;
		return this.listaTeste;
	&#125;
	
	public void addList&#40;&#41; &#123;
		LogClass.log&#40;this, "addList"&#41;;
		this.listaTeste.add&#40;new Message&#40;"Teste add", 2&#41;&#41;;
	&#125;

O estranho é que quando eu coloco ‘application’ ou ‘request’ no escopo funciona pefeitamente. So que eu preciso que
seja na ‘session’.

Agradeço desde ja pela atenção,
