title: CancellableFormController in Spring
body: <p>I'm trying to create a form which can be cancelled. I found that the class CancellableFormController exist. But couldn't find a good explanation how to use it. Its my understanding that you have to give a variable with the request. But how do you do this inside a spring form? If someone could help me implement this. Or just point me towards a good tutorial, as I was unable to find one.</p>
  
  <p>Thanks in advance,
  David</p>
