ZendFramework 2 - How to edit form data with fieldsets?

I'm trying to learn ZF2, and I am not able to edit the data in the edit form. I have two classes Pessoa and Endereco and I have a form to edit the data, but it only changes the data related to Pessoa, those about the Endereco is stored as blank.

And when trying to add a new record (add action) i get the following error:

Fatal error: Cannot use object of type Pessoa\Model\Pessoa as array in /opt/lampp/htdocs/cad/module/Pessoa/src/Pessoa/Model/Pessoa.php on line 23

Pessoa.php

class Pessoa
{
 public $id;
 public $nome;
 public $dtNasc;
 public $endereco;

 {
  $this->endereco = new Endereco();
 }
 public function exchangeArray($data)
 {
  $this->id      = (!empty($data['id'])) ? $data['id'] : null;
  $this->nome    = (!empty($data['nome'])) ? $data['nome'] : null;
  $this->dtNasc  = (!empty($data['dtNasc'])) ? $data['dtNasc'] : null;
  //$this->getEndercoInstance();
  $this->endereco->exchangeArray($data);
  /*if (isset($data["endereco"]))
  {
    if (!is_object($this->endereco)) $this->endereco = new Endereco();
    $this->endereco->exchangeArray($data["endereco"]);
   }*/
 }

 public function getArrayCopy()
 {
  $data = get_object_vars($this);

    if (is_object($this->endereco)) {
        $data["endereco"] = $this->endereco->getArrayCopy();
    }

    return $data;
 }

        // letting Zend\Di find out there's a $bar to inject where possible
        'parameters' => array('endereco' => 'Endereco\Model\Endereco'),
    )
 )
));
$config->configure($di);

$pessoa = $di->get('Pessoa');

Fatal error: Cannot use object of type Pessoa\Model\Pessoa as array in /opt/lampp/htdocs/cad/module/Pessoa/src/Pessoa/Model/Pessoa.php on line 23

Please, can anyone help me?

So let me explain better my self,

You are sending an array to the method

exchangeArray($data);

but $data is not an array;

Example of Array:

$data['username'] = 'someuser'; 
$data['email'] = '[email protected]'; 
$data['phone'] = '235346346';
print_r($data);die;

//output:
//Array ( [username] => someuser [email] => [email protected] [phone] => 235346346 )

Example Object:

$data['username'] = 'someuser'; 
$data['email'] = '[email protected]'; 
$data['phone'] = '235346346';

$object = (object)$data;
print_r($object);die;
//Output
//stdClass Object ( [username] => someuser [email] => [email protected] [phone] => 235346346 )

So i reproduce part of the code you have above and i gave to the method exchangeArray($data); of type Array and i got no errors then i gave to the method exchangeArray($object); and the result was Fatal error: Cannot use object of type stdClass as array in /blah/blah/... on line 39

So Basically in your method you are passing $data of type object and not Array
