title: "NOT IN" with HQL and Grails
body: <p>The following query should select all organisations that are not in the <code>excludedOrgs</code>:</p>
  
  <pre><code>Organisation.findAll("from Organisation o where o not in elements(?)", 
      [excludedOrgs])
  </code></pre>
  
  <p>All I get is an org.springframework.orm.hibernate3.HibernateQueryException telling me: <code>expecting IDENT, found '?'</code></p>
  
  <p>I'm using Grails 1.3.6.</p>
  
  <p>What's wrong with my query?</p>
