php - Symfony2 ignores form validation of collection -

i have problem symfony2 , validation of email addresses collection.

entity\user

/**  * user  *  * @orm\table()  * @orm\entity  */ class user {     /**      * @orm\id      * @orm\column(type="integer")      * @orm\generatedvalue(strategy="auto")      */     protected $id;      /**      * @var email[]      * @orm\onetomany(targetentity="email", mappedby="user", cascade={"all"}, orphanremoval=true)      * @assert\valid      */     private $emails;      public function __construct()     {         $this->emails = new \doctrine\common\collections\arraycollection();     }      public function getid()     {         return $this->id;     }      /**      * add emails      *      * @param email $emails      * @return user      */     public function addemail(email $emails)     {         if($emails->getemail() !== null && strlen($emails->getemail()) > 0)         {             $emails->setuser($this);             $this->emails[] = $emails;         }          return $this;     }      /**      * remove emails      *      * @param email $emails      */     public function removeemail(email $emails)     {         $emails->setuser();         $this->emails->removeelement($emails);     }      /**      * set emails      *      * @param email[] $emails      * @return user      */     public function setemails($emails)     {         $this->emails = array();          foreach($emails $email)         {             $this->addemail($email);         }          return $this;     }      /**      * emails      *      * @return email[]      */     public function getemails()     {         return $this->emails;     } } 

entity\email

/**  * email  *  * @orm\table()  * @orm\entity  */ class email {     /**      * @orm\column(name="id", type="integer")      * @orm\id      * @orm\generatedvalue(strategy="auto")      */     private $id;      /**      * @orm\column(name="email", type="string", length=255)      * @assert\email(checkmx = false)      */     private $email;      /**      * @var user      * @orm\manytoone(targetentity="user", inversedby="emails")      * @orm\joincolumn(name="user", referencedcolumnname="id", ondelete="cascade")      * @assert\notnull()      */     private $user;      public function getid()     {         return $this->id;     }      /**      * set email      *      * @param string $email      * @return email      */     public function setemail($email)     {         $this->email = $email;          return $this;     }      /**      * email      *      * @return string      */     public function getemail()     {         return $this->email;     }      /**      * set user      *      * @param user $user      * @return email      */     public function setuser(user $user = null)     {         $this->user = $user;          return $this;     }      /**      * user      *      * @return user      */     public function getuser()     {         return $this->user;     } } 

usertype

/**  * class usertype  */ class usertype extends abstracttype {     /**      * @param formbuilderinterface $builder      * @param array $options      */     public function buildform(formbuilderinterface $builder, array $options)     {         $builder             ->add('emails', 'collection', array(                 'type' => new emailtype(),                 'allow_add' => true,                 'allow_delete' => true             ))         ;     }      public function getname()     {         return 'user';     } } 

emailtype

/**  * class emailtype  */ class emailtype extends abstracttype {     /**      * @param formbuilderinterface $builder      * @param array $options      */     public function buildform(formbuilderinterface $builder, array $options)     {         $builder             ->add('email', 'email')         ;     }      /**      * @param optionsresolverinterface $resolver      */     public function setdefaultoptions(optionsresolverinterface $resolver)     {         $resolver->setdefaults(array(             'data_class' => 'entity\user'         ));     }      public function getname()     {         return 'email';     } } 

the assert annotation included in entities.

the problem can save form without valid email address.

• 123@example.org <- thats saved <- thats correct
• 123 <- thats saved <- thats not correct / no valid email address!
• an exception occurred while executing 'insert email (email, user) values (?, ?, ?)' params [null, null] <- if use "by_reference" = true error , if "by_reference" false have no error...

i hope me :)

run command terminal:

php app/console doctrine:schema:update --force
