###What happened:
- While trying to specify a format to a custom validator, it seems to skip the validation function 

###What was expected:
- When a format is specified it should call the function and pass the format 

### My code samples 
#### my custom validation: 
     
    Validator::add('sampleValid', function(&$value, $format = null, array $options = array()) { 
        var_dump("format = ", $format, "<br><br>", $options['format'], "<br><br>"); 
        exit(); 
    }

####  my call (without format specified) (validation function called)  : 
    $validations = array( 
        'inputName' => array( 
            array('sampleValid', 'message'=> 'this does not work the sample valid')
        )
    );
    return $document->save($this->request->data, array('validate' => $validations)); 

####  my call (with format specified) (validation function NOT called)  : 
    $validations = array( 
        'inputName' => array( 
            array(
                'sampleValid', 
                'message' => 'this does not work the sample valid', 'format' => 'string')
        )
    );
    return $document->save($this->request->data, array('validate' => $validations));
