Bug in Csla 4.5.700 - DataPortalOperationExtensions

I think there's a bug in the DataPortalOperationExtensions class in 4.5.700.  The line is 29:

       switch (operation)
      {
        case DataPortalOperations.Create:
          return AuthorizationActions.CreateObject;
        case DataPortalOperations.Fetch:
          return AuthorizationActions.GetObject;
        case DataPortalOperations.Update:
          return AuthorizationActions.EditObject;
        case DataPortalOperations.Delete:
          return AuthorizationActions.CreateObject;
        case DataPortalOperations.Execute:
          // CSLA handles Execute/CommandObject as Update operations
          // - this is the permission that the client DataPortal checks.
          return AuthorizationActions.EditObject;
        default:
          throw new ArgumentOutOfRangeException("operation");
      }

If operation is Delete is returning AuthorizationActions.CreateObject but I think it should be AuthorizationActions.DeleteObject instead.
