title: Error downgrade grails 2.0.0.RC1
body: <p>I'm upgrading my application to Grails 2.0.0 RC3.</p>
  
  <p>Now, I want to downgrade my application to Grails 2.0.0 RC1 but when I run it I have this error:</p>
  
  <pre><code>Error 500: Internal Server Error
  
  URI
      /directory/
  Class
      java.lang.IllegalStateException
  Message
      No thread-bound request found: Are you referring to request attributes outside of an actual web
      request, or processing a request outside of the originally receiving thread? If you are actually
      operating within a web request and still receive this message, your code is probably running
      outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or
      RequestContextFilter to expose the current request.
