title: Grails - How can I get a single error message
body: <p>How can I get a single error message from a command object in grails?</p>
  
  <p>all the examples I see are using similar to commandObject.errors.allErrors() but nothing if I only want the single error message to read into the controller and subsequently passed to the view.</p>
  
  <p>Any ideas?</p>
