title: CRM 2011 using pre-image in plugin
body: <p>I'm looking at using a pre-image for one of my plugins so i can get values in fields that haven't been changed. I've registered a pre-image for the entity in the plugin registration tool but when I've put some code in that tries to check it it doesn't find the image. So i was wondering what it was that I've missed that is stopping it from working. I've searched Google but couldn't really find anything, cant anyone help?</p>
  
  <p>Thanks</p>
