cakePHP validation errors not showing - validation

Question

So basically I have a view action in my users controller where the user can modify his information(username,first name, last name, email..) this form sends to another update action which does the saving stuff, problem is that when I submit the form and one or more fields don't meet the validation rules it doesn't show underneath each fields but the data doesn't save and
$this->User->validationErrors
outputs the errors.
my update action (accessed after submiting the form on view.ctp)
view.ctp:
<?php
echo $this->Form->create('User', array(
'inputDefaults' => array(
'div' => 'form-group',
'wrapInput' => false,
'class' => 'form-control'
),
'class' => 'well',
'url'=>array('controller'=>'users','action'=>'update'),
'id'=>'info-form'
));
?>
<fieldset>
<legend>Personal Information</legend>
<?php
echo $this->Form->input('id', array('value' => $userinfo['User']['id']));
echo $this->Form->input('User.username', array(
'label' => 'Username',
'value'=>$userinfo['User']['username']
));
?>
<td><?php echo $this->Form->error('username'); ?></td>
<?php
echo $this->Form->input('User.email', array(
'label' => 'E-mail',
'value'=>$userinfo['User']['email']
));
?>
<?php
echo $this->Form->input('User.fname', array(
'label' => 'First name',
'value'=>$userinfo['User']['fname']
));
?>
<?php
echo $this->Form->input('User.lname', array(
'label' => 'Last name',
'value'=>$userinfo['User']['lname']
));
?>
<?php
echo $this->Form->submit('Update', array(
'div' => 'form-group',
'class' => 'btn btn-success'
));
?>
</fieldset>
<?php echo $this->Form->end(); ?>
update function:
function update() {
$this->autoRender = false;
$this->User->set($this->request->data);
if ($this->request->is('post')) {
if ($this->User->save($this->request->data)) {
$this->Session->setFlash(__('Information updated Successfuly.'), 'alert', array(
'plugin' => 'BoostCake',
'class' => 'alert-success'), 'success');
return $this->redirect('/users/view/' . $this->request->data['User']['id']);
} else {
// $errors = $this->User->validationErrors; var_dump($errors);die;
$this->Session->setFlash(__('An error occured'), 'alert', array(
'plugin' => 'BoostCake',
'class' => 'alert-danger'), 'danger');
return $this->redirect('/users/view/' . $this->request->data['User']['id']);
}
} else {
$this->Session->setFlash(__('Request was not of POST type.'), 'alert', array(
'plugin' => 'BoostCake',
'class' => 'alert-danger'), 'danger');
return $this->redirect('/users/index/');
}

It's because you're redirecting after - that will make it lose the validation warnings.
