[fw-general] Re: Zend_Filter_Input fields meta command with arrays problem

I am having a problem with Zend_Filter_Input when attempting to validate an 
array of values using the fields meta command.  What happens is that ZFI 
passes the array of values to my filter which correctly returns true and 
then ZFI passes each value separately which fails.  Here is my 
code(simplified) pretty much straight from the doc:

$validators = array('password_check' => array('StringEquals',
               'presence' => 'required',
               'fields' => array('password0', 'password1'));

$input = new Zend_Filter_Input(array(), $validators, 
$this->getRequest()->getPost());
$input->addNamespace('Local_Validate');

if (!$input->isValid()) {

}

What happens is StringEquals is called three times, once with an array, 
and once with each string.  Some debug output dumping the value passed to 
my StringEquals validator produces the following:

array(2) {
 ["password0"] => string(9) "Testing1!"
 ["password1"] => string(9) "Testing1!"
}

string(9) "Testing1!"

string(9) "Testing1!"


So I looked into ZFI and it appears it handles arrays of fields (line 720 
in ZF 1.0.0 v5344) but then it continues to evaluate all fields in the 
data array *seperately* validating it against the current validator chain 
which happens to be the validator StringEquals which only validates 
arrays... which of course returns false.

Basically, it appears either I am missing something or having the fields 
meta command set to an array will not work if the validator validates that 
the value is in fact an array.  Anyone else come across this?  Should my 
validator simply return true if the value is not an array?  I'm not sure I 
care too much for that work around.  To me, if you pass the fields meta 
command with an array value it should only validate the array, not each 
seperately.  Any help is appreciated,
Thanks

The following if stmt fixes the issue:
// Added the below if check
if (1 == count($validatorRule[self::FIELDS])) {
   if (!$validatorRule[self::VALIDATOR_CHAIN]->isValid($value)) {
       $this->_invalidMessages[$validatorRule[self::RULE]] = 
$validatorRule[self::VALIDATOR_CHAIN]->getMessages();
       $this->_invalidErrors[$validatorRule[self::RULE]] = 
$validatorRule[self::VALIDATOR_CHAIN]->getErrors();
       unset($this->_validFields[$fieldKey]);
       $failed = true;
       if ($validatorRule[self::BREAK_CHAIN]) {
           return;
   }
}
