[fw-general] Zend Db Table Issue

[Rafael]

Hello,

I don't know if it is the right to ask however i have one issue that 
nobody else managed to solve it.

I'm using zend framework 1.11.3, PHP 5.3 and MySQL 5.1 configured with 
InnoDB engine. I'm trying to make a relationship between two tables
to apply cascade deletion but deletes only parental row and return me

Notice: Undefined index: numero_atual in 
C:\htdocs\Advocacia\library\Zend\Db\Table\Abstract.php on line 1197

It happens when i try to delete one row from the model 
Application_Model_ProcessosJudicial , I really can't see anything wrong 
in the code or...

I would be thankful if anyone check it for me

class Application_Model_ProcessosJudicial extends Zend_Db_table {

    protected $_name = "processos_judicial";
    protected $_dependentTables = array('Application_Model_Partes', 
'Application_Model_Andamentos');

    protected $_referenceMap = array(
        'Andamento' => array(
            'columns' => array('numero_atual'),
            'refColumns' => array('numero_atual'),
            'refTableClass' => 'Application_Model_Andamentos',
            'onDelete' => self::CASCADE,
            'onUpdate' => self::RESTRICT
        )
    );

}


class Application_Model_Andamentos extends Zend_Db_table {

    protected $_name = "processos_andamentos_judicial";

    protected $_referenceMap = array(
        'Andamento' => array(
            'refTableClass' => 'Application_Model_ProcessosJudicial',
            'refColumns' => array('numero_atual'),
            'columns' => array('numero_atual'),
            'onDelete' => self::CASCADE,
            'onUpdate' => self::RESTRICT
        )
    );

}
