How to position views with CCUIViewWrapper

I am using the code from http://www.cocos2d-iphone.org/forum/topic/6889 to add a UIView to the screen in a Cocos2d game. It works great in non-retina resolution (everything is positioned correctly), but in retina resolution the UIView is placed in a different location. The code I am using to add the view to the game is basically the same as the code from the website:

 UIView *myView = [[[UIView alloc] init] autorelease];
 myView.backgroundColor = [UIColor redColor];
 CCUIViewWrapper *wrapper = [CCUIViewWrapper wrapperForUIView:myView];
 wrapper.contentSize = CGSizeMake(100, 100);
 wrapper.position = ccp(50,50);
 [self addChild:wrapper];

The view appears 50px from the bottom and left corner in non retina and 0px from left and 100px up in retina.

The positioning for the wrapper in retina mode is ccp(320,0). No idea why, but it works.

    if ([[UIScreen mainScreen] respondsToSelector:@selector(scale)] == YES && [[UIScreen mainScreen] scale] == 2.00) {
        wrapper.position = ccp(320,0); //Retina
    } else {
        wrapper.position = ccp(160,240); //Normal
    }

The CCUIViewWrapper (at least in the form from the forum thread) does not use CC_CONTENT_SCALE_FACTOR(). That means it's not compatible with Retina displays.

You may be able to get around this by supplying properly scaled size and position, this may or may not work:

wrapper.contentSize = CGSizeMake(100 * CC_CONTENT_SCALE_FACTOR(), 
                                 100 * CC_CONTENT_SCALE_FACTOR());
wrapper.position = ccp(50 * CC_CONTENT_SCALE_FACTOR(), 
                       50 * CC_CONTENT_SCALE_FACTOR());
