Alloy - Adding a MapView (ti.map) inside an event

I'm getting an error message when attempting to add my MapView to my main component from within an event handler and an open window. I'm running on an emulator after looking up a few tricks to getting Maps v2 running. As I comment below, the map works fine when I add it to the main window from the main window evenlistener. But when I attempt to add it to the main window through globals and the other windows eventlistener it throws the error.

Let me give the example. In INDEX.JS I have a button that opens a modal window.

$.newRoundButton.addEventListener('click', function(e) {    
    if (Alloy.Globals.CurrentActivity != KUTIL.ACTIVITY.ACTIVEGAME) {
        /// Create Add Round Controller and Window View
        Alloy.Globals.NewRoundWindow.open();
        Alloy.Globals.AppWindow.add(Alloy.Globals.MapRoundView);
    } else {
        var dialog = Ti.UI.createAlertDialog({
            message: 'There is currently an active round.  Please end this round before starting another.',
            ok: 'Okay',
            title: 'Round Active'
        }).show();      
    }
});

Once the window is open I have another button / event handler to save a data to the database. Inside this event handler I'm attempting to add the mapview to the main appwindow:

$.saveButton.addEventListener('click', function(e) {
    if ($.courseName.value == '') {
        Ti.UI.createAlertDialog({
            title: 'Course Name',
            message: 'Course name can not be blank',
            ok: 'Okay'
        }).show();
        return null;
    }
 
    Titanium.App.fireEvent('app:newGameEvent', {
        coursedate: $.courseDate.value, 
        coursename: $.courseName.value,
        coursescore: 'NA'
    });
 
    // Close and dispose of Window
    Alloy.Globals.NewRoundWindow.close();
    Alloy.Globals.AppWindow.add(Alloy.Globals.MapRoundView);
});

** Note, that when I add the same line directly to the original button event handler it works without a problem. Which should be fine, I can get around the issue by adding it at the same time the window is opened and then removing it if the window cancel button is pressed (I think), but this should work no?
