title: call to .save() on domain class fails with no signature of method .save() in unit test
body: <p>I'm using Grails 1.3.2 in NetBeans. I have a very simple unit test that fails with this error:</p>
  
  <blockquote>
    <p>No signature of method: com.maxrecall.maxrequire.domain.Release.save()
    is applicable for argument types: (java.util.LinkedHashMap) values:
    [[flush:true]] Possible solutions: wait(), any(), wait(long),
    isCase(java.lang.Object), use([Ljava.lang.Object;), sleep(long)</p>
  </blockquote>
  
  <p>The relevant code is:</p>
  
  <pre><code>Release rel = new Release()
  ...
  rel.save(flush:true) 
  </code></pre>
  
  <p>The same code works in BootStrap.groovy. I have tried various variations on .save() (.Save with and without parameters. </p>
