title: On Wakanda Server, how can I access the current value of an attribute during a save / validate?
body: <p>I am building a <strong>"change log"</strong> feature for a <strong>Wakanda</strong> application. During the validate or save events on the server, I need to get access to the existing value of the attribute as it is in the datastore so I can record a before value and an after value.</p>
  
  <p>At this point, the only solution I have found is to run a query in the validate event and retrieve the entity fresh from the datastore. Perhaps this is the best / only solution?</p>
