Passivation beans must satisfy passivation dependencies

I have a problem with OmniFaces Viewscoped. Even when my Managedbean implements Serializable, I get the following error:

Passivation beans must satisfy passivation dependencies.

With some research, I found some answers to this problem, but with no success. I solved the serialization problem of my other class that I am embedding CDI.

Do my other classes really implement Serializable for Inject in my Managedbean?

Environment - WebSphere Application Server 8.5.5.2 - Apache MyFaces 2.0.2 - OmniFaces 1.7 - PrimeFaces 5.0

My class:

public class AgrupamentoAcoRN{

@Inject
public TbSiglaAcoAgrupadaDAO dao;

public void insereDados(TbSiglaAcoAgrupada tbSiglaAcoAgrupada) throws BancoDeDadosException{
    dao.insereRegistro(tbSiglaAcoAgrupada);
}
}

      

        
        
        
      

    

My Bean:

@Named("agrupamentoAcoMb")
@ViewScoped
public class AgrupamentoAcoMB implements Serializable{

/**
 * 
 */
private static final long serialVersionUID = 1L;

@Inject
private AgrupamentoAcoRN rn;
}
