Error Message On Register page

[julien_rouzot1]

Hi,

I would like show error message on my register page. But i don't found the solution.

In core we have : 

 if (!$response->getError()) {
            # Trying to load customer with the same email and return error message
            # if customer with the same email address exisits
            $checkCustomer = Mage::getModel('customer/customer')
                ->setWebsiteId($websiteId);
            $checkCustomer->loadByEmail($accountData['email']);
            if ($checkCustomer->getId() && ($checkCustomer->getId() != $customer->getId())) {
                $response->setError(1);
                $this->_getSession()->addError(
                    Mage::helper('adminhtml')->__('Customer with the same email already exists.')
                );
            }
        }

In CustomerController.php.

Now i would like show this errorMessage on my register.phtml.

I try some solutions like : 

<?php echo $this->getMessagesBlock()->toHtml() ?>

But i have 0 error message.

Someone can help me?

(Sorry for my english)

Thank you
