title: Error in breeze using EF 5 and calling stored procedure
body: <p>Getting an error client side with breeze: "Cannot call method 'map' of undefined" when trying to pull over some data. The difference between this action and one that works is that this action is calling a stored procedure and returning <code>ObjectResult&lt;T&gt;</code> instead of <code>DbSet&lt;T&gt;</code>.</p>
  
  <p>Might this be why I get an error? Using Chrome Developer tools, I do see that the breeze controller is returning json data.</p>
  
  <p>I have created a complex model type in the edmx for mapping the rows returned from the stored procedure.</p>
  
  <p>The action in the breeze controller has a return type of <code>IEnumerable&lt;T&gt;</code>.</p>
