Symfony2 : Validating a date using the Form Validator returns error

Question

I've added a element to my form which is of type 'date', this then has a validation rule which specifies that the form element value must be of type date, otherwise return an error. However rather than handling the validation, Symfony returns an Exception. See code below:

UserType.php

$builder->add('startdate', 'date', array(
              'label' => 'Start Date', 
              'widget' => 'single_text', 
              'format' => 'yyyy-MM-dd')
         );

Validation.yml

Acme\StoreBundle\Entity\User:
    properties:
        startdate:
            - Date:
                  message: You must specify a valid release date

Then when i type '2001-01-aaa' hoping that Symfony will notice the value is not in the right format and handle the error as specified, instead I get this

Failed to match value '2007-01-aaa' with pattern 'yyyy-MM-dd'
500 Internal Server Error - InvalidArgumentException 

Am I doing something wrong here?

Thanks in advance

It's a bug. It's now fixed and merged into 2.0 branch . It'll be hopefully included in next minor version.
