Sonata admin bundle email validation

Question

What is the best way to add an email validation in Sonata Admin?

I saw a discussion in Google groups about it and it says:

"Why force developers to repeat all validation constraints twice?"

https://groups.google.com/forum/?fromgroups=#!topic/sonata-users/xO64f_haMks

Is that true? Or is there a way to use the Symfony2 Validation at the same time?

Answer 1

Finally it works like this:

public function configureFormFields(FormMapper $formMapper)
{
    $formMapper
            ->add('email', 'email')
