title: Grails - how to get object domain fields without GORM additional fields?
body: <p>In order to have a validation on my domain class object, I need to get all the relevant fields that I need to have validation on.<BR>
  The exact fields I need are those who I defined by myself in my domain class and not those who GORM did.<BR></p>
  
  <p>I need to know how can I get those fields ?<BR>
  I mean, how to I get all the fields without 'id', 'version' and all other GORM generated fields. <BR>
  Thanks!</p>
