Struts2 funciona somente metodo execute da ActionSupport

Boa noite, estou com o mesmo problema que voce, e vou aproveitar seu topico para tirar uma duvida.

Tenho a minha classe UsuarioAction que nela tem os metodos:

@Validations(requiredStrings={
@RequiredStringValidator(fieldName="usuario.usuario", message="Campo usuario obrigatorio!!!"),
@RequiredStringValidator(fieldName="usuario.senha", message="Campo senha obrigatorio!!!")}, stringLengthFields={
@StringLengthFieldValidator(fieldName="usuario.usuario", minLength="5", message="Campo usuario: Tamanho minimo de 5 caracteres!!!"),
@StringLengthFieldValidator(fieldName="usuario.usuario", maxLength="15", message="Campo usuario: Tamanho maximo de 15 caracteres!!!")})
public class UsuarioAction extends ActionSupport{
	
	private UsuarioDao dao;
	private Usuario usuario;
	
	public UsuarioAction(){
		dao = new UsuarioDao();
	}
	
	@Action(value="/adiciona", results={
	@Result(location="/lista.jsp", name="ok"),
	@Result(location="/adiciona.jsp", name="input")})
	public String adiciona(){
		dao.adiciona(usuario);
		return "ok";
	}
	
	@Action(value="/busca", results={
	@Result(location="/mostraUsuario.jsp", name="ok")})
	public String busca(){
		usuario = dao.busca(usuario.getId());
		return "ok";
	}
	
	public void setUsuario(Usuario usuario){
		this.usuario = usuario;
	}

	public Usuario getUsuario(){
		return this.usuario;
	}
}

Minha app esta validando na hora de adicionar usuarios, porem quando encontra o /busca na url apresenta o seguinte erro:

Se eu retirar o ActionSupport e as validações funciona perfeitamente.

Alguem sabe me dizer o que fazer?

Se existe uma força de validar usando struts 2 que seja mais viavel
Se o correto é criar uma classe para cada metodo. Ex: AdicionaUsuarioAction, CarregaUsuarioAction, AlteraUsuarioAction

abs!

Cara no meu caso o problema e esse…
