title: Entity with Updates Mapped to Stored Procedure Not Tracking
body: <p>I have some views mapped in Entity Framework. Those entities have Insert/Update/Delete Stored Procedures mapped for modifications.</p>
  
  <p>The proxy entities seem not to be detecting changes properly. That is, if I check the ObjectStateManager for the ObjectStateEntry for my Person entity, and the State is Unchanged...if I update the FirstName property, the State remains Unchanged (it should be modified). These instances are indeed self tracking proxies...and more interestingly, if I change the value of a property on that entity that is mapped to an Association, the entity state does change to Modified...</p>
  
  <p>Other entities in the edmx model that are directly mapped to tables do not seem afflicted by this problem (any changes are correctly reflected in the ObjectStateEntry).</p>
  
  <p>What's going wrong here?</p>
