Back Button Not Displaying with NavigationWindow control

Hi all...

I am using the 3.2.2 SDK, and implementing a NavigationWindow. All seems fine, but one problem I see within my application is that when using this, the Back button doesn't display within the UI, but if I click where the back button should be, it does in fact close the child window and go back to the parent.

Has anyone seen similar behavior in their apps?

I am instantiating as such:

childWindow = Alloy.createController('CM/types', {
        id: uid,
        module : 'aT'
    }).getView();
 
 
   $.aTNavGroup.openWindow(childWindow);

Talk soon Chris
