'Done' button not visible in the Modal view - iphone

Question

I am trying to present a modal view from one of my view. The presenter view is already shown as a modal from a custom view. My problem is that I am not able to see the 'Done' button on the new Modal view presented. Below is my code. Am I missing something?
UIViewController *aViewController = [[UIViewController alloc] init];
UINavigationController *aNavigationController = [[[UINavigationController alloc] initWithRootViewController:aViewController] autorelease];
[aNavigationController.navigationBar setBarStyle:UIBarStyleBlack];
UIBarButtonItem *aBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(dismissMe)];
[aNavigationController.navigationItem setLeftBarButtonItem:aBarButtonItem];
MyView *aView = [[MyView alloc] initWithFrame:self.view.frame];
[aViewController.view addSubview:aView];
[self presentModalViewController:aNavigationController animated:YES];
[aViewController release];
- (void)dismissMe {
[self dismissModalViewControllerAnimated:YES];
}

If I understand weel the question, you can try a solution like this:
Write this in the viewDidLoad or init method of the modal view controller you want to show from the actual view:
UIBarButtonItem *done = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self selector:#selector(dismissMe)];
self.navigationController.leftBarButtonItem = done;
and implement you dismissMe method.
Instead, in the presenter controller write this where you want to present the new modal controller:
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:controllerYouWantToShow];
[self presentModalViewController:navController animated:YES];
Obviusly, controllerYouWantToShow is a pointer/variable pointing your view controller you want to show... I usually do this to solve a problem like yours... However, check the code because I havent't tested it :)
Hope it helps!
