Description

Sample code from pastebin: http://pastebin.com/QeeGwMtF

// this sets the background color of the master UIView (when there are no windows/tab groups on it)
Ti.UI.setBackgroundColor('#000');


// refresh button
var refreshButton = Ti.UI.createButton({
	systemButton: Titanium.UI.iPhone.SystemButton.REFRESH
});

// add button
var addButton = Ti.UI.createButton({
	systemButton: Titanium.UI.iPhone.SystemButton.ADD
});



// create navgroup
var win = Ti.UI.createWindow();

var win1 = Ti.UI.createWindow({
	title: 'test',
    leftNavButton: refreshButton,
    rightNavButton: addButton
});

var nav = Ti.UI.iPhone.createNavigationGroup({
   window: win1
});

win.add(nav);

win.open();


addButton.addEventListener('click', function() {
	var addWindow = Ti.UI.createWindow();
	nav.open(addWindow, {
		animated: true
	});
});

Click the + button, then click Back, and see the leftNavButton fade-in twice.

There is a Helpdesk ticket reporting this problem: http://developer.appcelerator.com/helpdesk/view/75911">http://developer.appcelerator.com/helpdesk/view/75911

Here is a simple runnable example:

     var win = Titanium.UI.createWindow();
       var win1 = Titanium.UI.createWindow({
           backgroundColor:"red",
           title:"Red Window"
       });
   
       var navBtn = Ti.UI.createButton({title:'button'});
       win1.leftNavButton = navBtn;
   
       var nextBtn = Ti.UI.createButton({
           title:'go to next window',
           width:200,
           height:50
       });
       win1.add(nextBtn);
   
       var nav = Titanium.UI.iPhone.createNavigationGroup({
          window: win1
       });
       win.add(nav);
       win.open();
   
       nextBtn.addEventListener('click', function(){
           var win2 = Titanium.UI.createWindow({
               backgroundColor:"blue",
               title:"Blue Window"
           });
           nav.open(win2,{animated:true});
       });

Any updates?

This issue has been fixed as a part of some other fix. It is very possible that this fix is available in releases prior to 2.1.0 release.
