$sender->send($message);

the error message is :

Catchable Fatal Error: Argument 1 passed to FOS\MessageBundle\Sender\Sender::send() must implement interface FOS\MessageBundle\Model\MessageInterface, instance of FOS\MessageBundle\MessageBuilder\NewThreadMessageBuilder given, called in /projet/pivotalpartnersbo/src/Application/Sonata/MessageBundle/Controller/MessageController.php on line 32

Answer 1

The message must me created.

Something like $message = $builder->newThread(); or $message = $builder->reply($thread);

While you apparently have just $message = $builder;

Answer 2

thanks qooplmao and yonel i just find the mistake, that i forget to extend the BaseMessage in the class of $message object. BaseMessage implement the MessageInterface.
