title: Grails: showing error message in web flow
body: <p>I want to show my domains error message in .gsp but somehow I'm not able to..
  In my Controller, </p>
  
  <pre><code>class SomethingController {
      def index(){
          redirect(action: "create")
      }
  
      def createFlow = {
          stepOne {
              on("submit"){
                  domain = new Domain(firstColumn: params.firstColumn)
  
                  if(!domain.validate()){
                      return error()
                  } else {
                      return success()
                  }
              }.to "stepTwo"  
          }
          stepTwo {
              ...
          }
      }
  }
  </code></pre>
  
  <p>And in my .gsp, I have:</p>
  
  <pre><code>&lt;g:renderErrors bean="${domain}" /&gt;
  </code></pre>
  
  <p>I'm definitely sure that if i "println domain.errors" i get validation error message. However, when failed in stepOne, I don't see any error message as well as ${domain.errors} outputs 0 errors. </p>
  
  <p>Please help... this might be a stupid mistake I'm doing...</p>
