problem with iOS 4.2 when user press the list view item to go to UIwebview page and the navigation button disappears on the second visit

My app is a Navigation based application. The main menu contains the list view items. if I clicks one of them, it goes to next view which in this case take me to UIwebview embedded web site. Everything is looking great. I can view the content of web page, the navigation control back button which takes to the main menu if I press it. However, I'm having issue when I try to go back to main menu if i visit that subview the second time. It loads the content of UIwebview web page, but the navigation button is gone and won't let me go back to main menu. This problem only appears on latest iOS 4.2 version. Otherwise it works great on 3.1 to 4.1. I would appreci开发者_JS百科ate any hints or inputs. Note this seems not working for subview using UIWebview embedded web content. I don't have any issue with other subviews

Can you show us the code ? Did you try this: self.navigationItem.hidesBackButton = NO; in viewDidLoad method where you are adding UIWebView to your view..
