[fw-general] Zend_Form_Decorator_Errors question about imlpementation

[umpirsky]

Hi.

Zend_Form_Decorator_Errors in render method line #53 do:

$errors = $element->getMessages();
        if (empty($errors)) {
            return $content;
        }

why is presence of an error done this way and not 

        if (!$element->hasErrors()) {
            return $content;
        }

I'm asking because I'm implementing my custom error decorator.

Regards,
Saša Stamenkovič.
