I'm getting this error on a given view.
Warning (2): range() [function.range]: step exceeds the specified
range [CORE\cake\libs\set.php, line 235]

Line 13 of my controller is:
$this->set('interno', $this->Interno->read(null, $id));
This is the view method:
function view($id = null) {
if (!empty($id)) {
$this->set('interno', $this->Interno->read(null, $id)); //
line 13
$internacoes = $this->Interno->data['Internacoes'];
$data_in = new DateTime($internacoes[0]['data_entrada']);
if (empty($internacoes[0]['data_saida'])) {
$data_out = new DateTime;
} else {
$data_out = new DateTime($internacoes[0]
['data_saida']);
}
$duracao = $data_in->diff($data_out);
$this->set('duracao', $duracao);
} else {
$this->redirect(array('action' => 'index'));
}
}
This is my model:
class Interno extends AppModel {
var $name = 'Interno';
var $helpers = array('Time');
var $validate = array(
'nome' => array('rule' => 'notEmpty'));
var $hasMany = array(
'Internacoes' => array(
'className' => 'Internacao',
'order' => 'Internacoes.created DESC'),
'Visitas' => array(
'className' => 'Visita',
'order' => 'Visitas.data DESC'),
'Enderecos' => array('className' => 'Endereco'));
var $hasAndBelongsToMany = array(
'Contato' => array (
'className' => 'Contato',
'joinTable' => 'contatos_internos',
'foreignKey' => 'interno_id',
'associationForeignKey' => 'contato_id'));
}
My suspicions are on the DateTime and date_diff usage, because when I
take that part of the code off, it works smoothly with no warnings.
Any ideas of what could be going on here?
