Forms with a translator do not translate element labels in the list of form errors. I believe the problem exists in Zend_Form_Decorator_FormErrors::renderLabel. Following a similar pattern to Zend_Form_Decorator_Label, the following patch should provide the functionality (patch against trunk r15870):

Index: library/Zend/Form/Decorator/FormErrors.php

--- library/Zend/Form/Decorator/FormErrors.php (revision 15870) +++ library/Zend/Form/Decorator/FormErrors.php (working copy) @@ -351,6 +351,10 @@ $label = $element->getName(); }

• if (null !== ($translator = $element->getTranslator())) {
• $label = $translator->translate($label);
• }
• return $this->getMarkupElementLabelStart() . $view->escape($label) . $this->getMarkupElementLabelEnd();

Thanks
