Lazy collections cannot be used if they have been deserialized

Question

I'm using ORM Lite in my project, and I have a situation where step by putExtra the intent of a Person object, which has a Collection of Email object, but when I try to read this Collection which is like LazyLoad (eager = false) below follows the models and the code used to retrieve the collection of Email:

public class Pessoa implements Serializable{

    @DatabaseField(generatedId=true)
    private int id;

        ...

    @ForeignCollectionField(eager=false)
    private Collection<Email> emails;

        ...
}
public class Email implements Serializable{

    @DatabaseField(generatedId=true)
    private int id;

    ...

    @DatabaseField(foreign=true)
    private Pessoa pessoa;

       ...
}

Retrieving the Collection:

if(getIntent().hasExtra("Pessoa")){
       pessoa = (Pessoa) getIntent().getSerializableExtra("Pessoa");

Iterator<Endereco> iterator = pessoa.getEnderecos().iterator();
while(iterator.hasNext()){
        Endereco end = iterator.next();
        Log.e("ENDERECO",end.getLogradouro());
}

I get the following error:

The error clearly says what the problem is, but it has another way to pass the Person object to another intent and that works with lite ORM?

Thank you!
