使用fosuserbundle重写更改密码表单

我使用FOSuserBundle，我已经覆盖了注册和登录表单，它们工作得很好，但覆盖更改密码表单不起作用。它仍然是从vendor ' friendsofsymfony ' user-bundle ' FOS ' UserBundle ' Form ' Type ' ChangePasswordFormType

ChangePasswordFormType.php

<?php
 namespace Boutique'UserBundle'Form'Type;
 use Symfony'Component'Form'FormBuilderInterface;
 use Symfony'Component'OptionsResolver'OptionsResolverInterface;
 use Symfony'Component'Form'AbstractType;
 use Symfony'Component'Security'Core'Validator'Constraint'UserPassword as OldUserPassword;
 use Symfony'Component'Security'Core'Validator'Constraints'UserPassword;
 use FOS'UserBundle'Form'Type'ChangePasswordFormType as BaseType;
 class ChangePasswordFormType extends BaseType
 {
private $class;
/**
 * @param string $class The User class name
 */
public function __construct($class)
{
    $this->class = $class;
}
public function buildForm(FormBuilderInterface $builder, array $options)
{
    if (class_exists('Symfony'Component'Security'Core'Validator'Constraints'UserPassword')) {
        $constraint = new UserPassword();
    } else {
        // Symfony 2.1 support with the old constraint class
        $constraint = new OldUserPassword();
    }
    $builder->add('current_password', 'password', array(
        'label' => 'actuelle',
        'translation_domain' => 'FOSUserBundle',
        'mapped' => false,
        'constraints' => $constraint,
    ));
    $builder->add('plainPassword', 'repeated', array(
        'type' => 'password',
        'options' => array('translation_domain' => 'FOSUserBundle'),
        'first_options' => array('label' => 'form.new_password'),
        'second_options' => array('label' => 'form.new_password_confirmation'),
        'invalid_message' => 'fos_user.password.mismatch',
    ));
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => $this->class,
        'intention'  => 'change_password',
    ));
}
public function getName()
{
    return 'boutique_user_change_password';
}
}
