title: "Core Data could not fulfill a fault.." error
body: <p>I am developing an application in cocoa. I am facing a critical problem.</p>
  
  <p>I am deleting entries of an object named "Directory" in Core Data using the following code: </p>
  
  <pre><code>NSEnumerator *tempDirectories = [[folderArrayController arrangedObjects] objectEnumerator];
  id tempDirectory;
  while (tempDirectory = [tempDirectories nextObject]){
      [managedObjectContext deleteObject:tempDirectory];
  }
  </code></pre>
  
  <p>But sometimes an exception like "Core Data could not fulfill a fault.." occurs while trying to save after deletion. I am using the code <code>[managedObjectContext save];</code></p>
  
  <p>I am new in Core Data... Looking forward to a solution.</p>
