Symfony Multiple Post Validators
I'm using Symfony 1.4 and am having an issue using multiple form validators.

For part of the form, I need to make sure the email address is valid AND unique.
Here's the code I'm trying to use to do this:

    $this->validatorSchema['email_address'] = new sfValidatorAnd(
        array(
            new sfValidatorEmail(),
            new sfValidatorPropelUnique(array('model' => 'Users', 'column' => 'email_address')
        ),

    ));

As far as I can tell, this SHOULD work. However, when I post the form, I get the following error message

> You must pass an array parameter to the clean() method (this validator can only be used as a post validator).

Any ideas or suggestions?
