title: Objective-C error: Property 'active' is a scalar type on class 'Routine'. Cannot generate a getter method for it
body: <p>I'm getting the above error when the following runs in the iphone simulator (3.0 OS):</p>
  
  <pre><code>@interface Routine : NSManagedObject {
  
  }
  
  @property (nonatomic) BOOL active;
  
  @implementation Routine
  @dynamic active
  @end
  </code></pre>
  
  <p>As you can see, I'm subclassing NSManagedObject because I'm using Core Data. In my data model, "active" is an option attribute of type Boolean.</p>
  
  <p>What am I doing wrong here?</p>
  
  <p>Thanks!</p>
