private function getAllFormErrors($children, $template = true) {
        foreach ($children as $child) {
            if ($child->hasErrors()) {
                $vars = $child->createView()->getVars();
                $errors = $child->getErrors();
                foreach ($errors as $error) {
                    $this->allErrors[$vars["name"]][] = $this->convertFormErrorObjToString($error);
                    
                }
            }

            if ($child->hasChildren()) {
                $this->getAllErrors($child);
            }
        }
    }

    public function getAllErrors($children, $template = true) {
        $this->getAllFormErrors($children);
        return $this->allErrors;
    }

    private function convertFormErrorObjToString($error) {
        $errorMessageTemplate = $error->getMessageTemplate();
        foreach ($error->getMessageParameters() as $key => $value) {
            $errorMessageTemplate = str_replace($key, $value, $errorMessageTemplate);
        }
        return $errorMessageTemplate;
    }
