Zend_Form -> Nicely change setRequired() validate message

Question

Say I create a text element like this:

$firstName = new Zend_Form_Element_Text(\'firstName\');
$firstName->setRequired(true);

Whats

Answer 1

One small issue. This code:

$zipCode->setLabel('Postal Code')
        ->addValidator('StringLength', true, array( 5, 5 ) )
        ->addErrorMessage('More than 5')
        ->addValidator('Digits', true)
        ->addErrorMessage('Not a digit');

Will generate both error messages if either validation fails. Isn't is supposed to stop after the first fails?
