PopToRootViewControllerAnimated toolbar does not update correctly

Question

I have a UITabBarController whose tabs is a UINavigationController. I initialized every navigationController:

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

Then deploy the navigation controller with:

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

I want to appear at the root of my navigation controller (s) when the user clicks on the tabBar tab.

 [delegate.navigationController2 popToRootViewControllerAnimated:NO];

This seems to work fine when I only pushViewController at one level, but it fails when I expand several levels in my navigation controller. What happens is that it appears to the root, but does not contain my hand stand or name:

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

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

If I do not poptoroot and just use the NavigationControlls navigation button, everything works correctly.

I registered my view controllers before and after I poptoroot

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

, :   MainCountryController: 0x3d53650
