• Why are you testing isPopover as a string literal? Wouldn't you want to say if (isPopover == true) ?

• Why bother testing? Just make it so…just remove the conditional check and hide the popover no matter what

• Still wont hide it. =/

• Is navPopover in scope at the time? Add this to the orientationchange to see if you have access to it. It's possible that navPopover was defined inside a function or some other context and isn't defined by the time the orientationchange occurs.

  Ti.API.info(navPopover);
  

• Ti.API.info doesn't work for me in 1.4.

  But navPopover is defined outside of a function and is called when orientation is in portrait. So is it possibale that when going from portrait to landscape it becomes undefined?

• Here is a snippet of code that can be used to see the issue I'm having.

  var masterWindow = Ti.UI.createWindow ({
      backgroundColor:'#000'
  });
  
  var navButton = Ti.UI.createButton({
      title:'A Button'
  });
  
  var detailWindow = Ti.UI.createWindow({
      backgroundColor:'#fff',
      top:0,
      title:'Test',
      leftNavButton:navButton
  });
  
  var masterDetail = Ti.UI.iPhone.createNavigationGroup(
  {
    window: detailWindow,
      right:0,
      top:0
  });
  
  masterWindow.add(masterDetail);
  
  var navPopover = Ti.UI.iPad.createPopover({
      width:320,
      height:850,
      navBarHidden:true
  });
  
  navButton.addEventListener('click', function(){
      navPopover.show({view:navButton});
  });
  
  Ti.Gesture.addEventListener('orientationchange',function(e)
  {
      if(e.orientation == 3 || e.orientation == 4)
      {
          navPopover.hide();
      }
  });
  
  masterWindow.open();
  

• Your code looks fine. It looks like there is a deeper issue here. If you do this.

    Ti.API.info(navPopover.visible);
  

  You don't get true or false, you get NULL in some versions of Titanium.

  There are actually a couple bugs. With the most recent builds the app will crash if the popover is visible and the device is rotated. It also refuses to hide a popover when you call the hide method and the visible property doesn't really do what you'd think it would do.

• I have an addendum. The docs refer to an options parameter which it turns out is not optional. Because you didn't specify options, the call didn't execute as you would expect. I verified this by setting a breakpoint in the Objective-C and found that hide was never called unless I sent options. Now that I send options, the hide method tries to execute however different versions of the API seem to behave in different ways.

  BTW - The right call to hide would look like this:

        navPopover.hide({animated: true});
