title: Spring Web Flow Passing Model Object from Flow to Controller
body: <p>What is the proper way to pass a model object used in Spring Web Flow to a Controller?</p>
  
  <p>My use case is as follows:</p>
  
  <p>I have a flow and the end state displays a model object that contains some calculated results.  That works good.  I also have a link on the page to generate a pdf to display the results.  That too works fine if I manually set the model object.</p>
  
  <p>So how do I get the model object used in the flow to the controller?  Or is there a cleaner way to view pdfs using webflow?</p>
  
  <p>Thanks</p>
