in app.js

var myObj = {};
myObj.prop1 = 'foo';
myObj.printValues = function()
{

Ti.API.info('values win1.myObj.prop1 ' + win1.myObj.prop1);

}

var win1 = Ti.UI.createWindow({
url: 'win1.js', })

win1.myObj = myObj;
win1.open();

in win1.js

var win = Ti.UI.currentWindow;

var openButton = Ti.UI.createButton({
title: 'foo Me' });

win.add(openButton);

openButton.addEventListener('click', function(e) {

win.myObj.printValues(); win.myObj.prop1 = 'bar'; win.myObj.printValues();

});

value of prop1 remains 'foo'
