title: Grails - Controller chain and model disapearance
body: <p>I am trying to use the <code>chain</code> feature to call an other method and render a merged model.
  This is how I call the <code>chain</code>:</p>
  
  <p><strong>Controller: emailToNotify, Method: sendEmailConfirmation</strong></p>
  
  <pre><code>if (someCommandObject.hasErrors())
                  chain(controller: "creditProvider", action: "rank", model: [emailToNotify: epnc, somethingToDisplay: "Boom !!!!"])
  </code></pre>
  
  <p>This is how my <code>rank</code> method end-up in my <code>creditProvider</code> controller:</p>
  
  <p><strong>Controller: creditProvider, action: rank</strong></p>
  
  <pre><code>render (view: 'simulateResult', model: [bim : bam, boom : bimbamboom])
  </code></pre>
  
  <p>I do not manage to call <code>${emailToNotify}</code> or <code>${somethingToDisplay}</code> from my <code>simulateResult.gsp</code> view. </p>
  
  <p>I have already used <code>chain</code> before in this exact same way, and it was (and still is) working properly. </p>
  
  <p><strong>Any idea why the model is not passed properly to the view ?</strong> </p>
  
  <p>Any help most welcome as always.
  All the best,</p>
