public function add($question_id = null) {    
    if ($this->request->is('post')) {
            $this->loadModel('Question');
            $this->Answer->set(array('question_id'=>$question_id));

        $this->Answer->create();

        $user = $this->Question->find('all',array('fields' => 'Useri.email',
                                                  'joins' => array(array('conditions' => array('Useri.id = Question.user_id'),
                                                                                   'table' => 'users',
                                                                                   'alias' => 'Useri',
                                                                                   'type' => 'INNER'))));


            $email = new CakeEmail();
            $email->config('server');
            $email->template('answer');
            $email->viewVars(array(
                    'to'=>$user['User']['email']
            ));
            $email->to($user);
            $email->from(array('gais@wahanaartha.com' => 'IT Sharing Knowledge Team'));
            $email->subject('Sharing Knowledge Notification');
            $result=$email->send();

        if ($this->Answer->save($this->request->data)) {
            $this->Question->updateAll(array('Question.status' => '1'),  
                           array('Question.id' => $question_id));
            $this->Session->setFlash(__('The answer has been saved.'));
            return $this->redirect(array('controller' => 'questions', 'action' => 'view', $question_id));
        } else {
            $this->Session->setFlash(__('The answer could not be saved. Please, try again.'));
            return $this->redirect(array('controller' => 'questions', 'action' => 'view', $question_id));
        }
    }
    $questions = $this->Answer->Question->find('list');
    $users = $this->Answer->User->find('list');
    $this->set(compact('questions', 'users', 'tests'));
}

Concording with CakeEmail :

**to( ) public
To
Parameters
mixed $email optional null
Null to get, String with email, Array with email as key, name as value or email as value (without name)
string $name optional null
Returns
mixed
mixed**

So your $user array must like : ["email1@mail.com"=>"Name User", "email2@mail.com"=>"Name User2"] or a string : "email@mail.com" .

Try this ! and tell me more about.

(try to set $email->to(array('mail@mail.com'=>'Name User') );

If isnt work , please tell us more about your bug
