popToRootViewControllerAnimated toolbar not correctly updating.

Question

I have a UITabBarController whose tabs are UINavigationController. I have initialized each navigationController by:

 iPhoneApp *appDelegate = (iPhoneApp *)[[UIApplication sharedApplication] delegate];
 [appDelegate.navigationController2 initWithRootViewController:countryController];

I then drill down the navigationController with:

[self.navigationController pushViewController:myViewController animated:YES];

I want to pop to the root of my navigationController(s) when the user clicks on a tabBar tab.

 [delegate.navigationController2 popToRootViewControllerAnimated:NO];

This seems to work great when I only pushViewController one level, but fails when I drill down multiple levels in my navigationController. What happens is that it pops to root but doesn't contain my Root's backbutton or title:

 self.navigationItem.title = @"My title";
 self.navigationItem.hidesBackButton = YES;

 UIBarButtonItem *cancelButton = [[UIBarButtonItem alloc] initWithTitle:@"Back"
                                                         style:UIBarButtonItemStyleDone
                                                         target:self
                                                     action:@selector(handleBack:)];

if I don't poptoroot and just use the navigationControlls back button, everything works correctly.

I logged my viewControllers before and after i poptoroot

before: MainCountryController: 0x3d53650, IndividualCountryMfgViewController: 0x3d67d50, IndividualCountryProductViewController: 0x3d60870

after: MainCountryController: 0x3d53650

it's the right view, but wrong toolbar title and backbutton.

Anyone have any ideas? Thanks for your help.

I got this working by disconnecting my navigation controllers from IB an just creating them programatically.
