===== Flash Communicating Between Actions =====
Here are two ways to flash a message on a view:
  - ''redirectTo'' causes http to write a new page.  You must use it to get ''flash'' to work on your next page.\\ 
    * Controller<code php>
$this->flash['notice'] = $this->t('User was successfully updated.');
$this->redirectTo(array('action' => 'show', 'id' => $this->user->getId()));</code>
    * View<code html>
<%= flash %></code>
  - When a scaffold is generated, it creates view code as you see in this section.  If you want Akelos to handle the navigation from the controller to the view, you must use ''flash_now'': \\ 
    * Controller<code php>
$this->flash_now['notice'] = $this->t($msg);</code>
    * View<code html>
 {?flash-notice}<div class="flash_notice">{flash-notice}</div>{end}</code>
