Trying to ignore a property with SMXObject

gistfile1.m

  MyObject *one = [[MyObject alloc] init];
  one.message = @"Hello World!";
  one.intValue = 1;

  MyObject *two = [MyObject objectFromArchive:[one archivedObject]];
  NSLog(@"Retrieved Message: %@", two.message);
  NSLog(@"Should be 0, but is 1: %d", two.intValue);


@interface MyObject : SMXObject

@property (nonatomic, strong) NSString *message;
@property (nonatomic, assign) NSUInteger intValue;
@end
@implementation MyObject

@synthesize message;
@synthesize intValue=_intValue;

- (id) encodeValue:(id)value forProperty:(NSString *)property
{
  if ([property isEqualToString:@"intValue"]) {
    return nil;
  }
  return value;
}
