title: Caché OREF Error - Getting More Information
body: <p>I'm am trying to integrate with a Caché Web Service and I'm getting an error message similar to:</p>
  
  <blockquote>
    <p>ERROR #5002: Cache error: &lt;INVALID OREF>zMethodName+45^AA.wsClass.8</p>
  </blockquote>
  
  <p>I do have have access to the code (albeit just a copy, so read-only), and I'm trying to decipher what the error could be pointing me to.</p>
  
  <p>So does the number 45 and/or 8 mean anything? I've tried to see if it is pointing to a line number or offset from the method and I can't seem to pin point anything.</p>
  
  <p>How might I be able to figure more out from this error?</p>
