title: Entity Framework Non-nullable column is mapped to a nullable entity property
body: <p>I am getting this nullable column error message in Entity Framework 4.1 - when the column is not actually nullable: </p>
  
  <pre><code>Non-nullable column MyView.RunningTotal in table TransactionListView 
  is mapped to a nullable entity property.
  </code></pre>
  
  <p>But you can see from the screenshots below that the column is not nullable and that the entity property is not nullable either.  So why is this error occurring?</p>
