Titanium WTF: Window children property

app.js

var win = Ti.UI.createWindow({ backgroundColor: "#fff", navBarHidden: true, layout: 'horizontal' });
    
    var view = Ti.UI.createView({
    	layout: 'horizontal'
    });
    
    var label1 = Ti.UI.createLabel({
    	top: 150,
    	left: 50,
    	text: 'Testing 1 ...',
    	height: '75dp',
    	width: '50%',
    	backgroundColor: "#000"
    });
    
    var textField = Ti.UI.createTextField({
    	top: 150,
    	left: 50,
    	width: '150dp',
    	height: '75dp',
    });
    
    var label2 = Ti.UI.createLabel({
    	top: 150,
    	left: 50,
    	text: 'Testing 2 ...',
    	height: '75dp',
    	width: '50%',
    	backgroundColor: "#000"
    });
    
    var picker = Ti.UI.createPicker({
    	top: 150,
    	left: 50,
    	height: '75dp',
    	backgroundColor: "#999",
        selectionIndicator : true
    });
    
    var data = [];
    
    data[0] = Ti.UI.createPickerRow({ title:'Bananas' });
    data[1] = Ti.UI.createPickerRow({ title:'Strawberries' });
    data[2] = Ti.UI.createPickerRow({ title:'Mangos' });
    data[3] = Ti.UI.createPickerRow({ title:'Grapes' });
    
    picker.add(data);
    
    view.add(label1);
    view.add(textField);
    view.add(label2);
    view.add(picker);
    
    win.add(view);
    
    win.addEventListener('open', function() {
    	Ti.API.info('View');
    	Ti.API.info(typeof view.children); // "object" - should be "[object Array]"
    	Ti.API.info(typeof view._children); // "undefined" - OK
    	Ti.API.info(view.children.length); // "4"  - OK
    	Ti.API.info('Window');
    	Ti.API.info(typeof win.children); // "object" - should be "[object Array]"
    	Ti.API.info(typeof win._children); // "object" - should be "undefined"
    	Ti.API.info(win.children.length); // "0"  - should be "1"
    	Ti.API.info(win._children.length); // "1" - should throw an exception since "_children" should be undefined
    });
    
    win.open();

Ah, no worries, I was going through your public gists and came across this one. :) Thats all.

The _children you are talking about, could be some private Titanium API, I mean, internal that somehow found its way to the JS.
