title: CakePhp Refreshing page
body: <p>I have the following problem in Cakephp:
  I maded a CMS to edit the content of a website with CakePhp. Now when I change the content in my form and I click Save then he shows again the data from before the form was changed. 
  In the database everything saved well and if I refresh the page also he shows the right data.</p>
  
  <p>I know I can render a new page or redirect to another page, but I liked to just show a message with setFlash and that's it. Someone can help me out?</p>
  
  <p>Thanks in advance</p>
