Forms Symfony2 FOSUserBundle覆盖表单：表单\提交前出现错误（表单）？

从模板单击此按钮时：

<form action="{{ path('fos_user_registration_register') }}" method="post">        
   <button class="btn btn-small btn-success" type="submit">S'inscrire</button>                     
</form> 

由于某些原因，所有验证消息都会出现（例如请输入用户名），尽管我没有提交表单

有什么解释吗

如何自定义FOSUser模板并重定向错误消息，而不使其显示或更改消息或显示？

最后，我覆盖了注册内容视图，如下所示：

   <form action="/projet_etienne_auth/web/app_dev.php/register/"  method="POST"     class="fos_user_registration_register">
  {{ form_errors(form) }}
  {{ form_widget(form._token) }}
 <div>
<label for="fos_user_registration_form_username" class="required">Nom d&#039;utilisateur :</label>
<input type="text" id="fos_user_registration_form_username" name="fos_user_registration_form[username]" required="required" maxlength="255" pattern=".{2,}" /></div>
<div>
    <label for="fos_user_registration_form_email" class="required">Adresse e-mail :</label>
    <input type="email" id="fos_user_registration_form_email" name="fos_user_registration_form[email]" required="required" /></div>

<div>
    <label for="fos_user_registration_form_plainPassword_first" class="required">Mot de passe :</label>

    <input type="password" id="fos_user_registration_form_plainPassword_first" name="fos_user_registration_form[plainPassword][first]" required="required" />
</div>
<div><label for="fos_user_registration_form_plainPassword_second" class="required">Vérification :</label>
    <input type="password" id="fos_user_registration_form_plainPassword_second" name="fos_user_registration_form[plainPassword][second]" required="required" />
