[TIMOB-7240] Android: OptionDialog can't be called several times after a tabgroup is opened and closed.

var w = Ti.UI.createWindow({
	backgroundColor: 'red',
	fullscreen: false,
	exitOnClose: true
});

var b = Ti.UI.createButton({
	height: 50,
	title: 'click'
});

b.addEventListener('click', function(e) {
	var optDlg = Ti.UI.createOptionDialog({
		title: 'choose',
		options: ['open', 'dismiss']
	});

	optDlg.addEventListener('click', function(e) {
		if (e.index===0) {
			var t = Ti.UI.createTabGroup(),
				w1 = Ti.UI.createWindow({
					title: 'blue',
					backgroundColor: 'blue'
				}),
				b1 = Ti.UI.createButton({
					title: 'close'
				}),
				t1 = Ti.UI.createTab({
					title: 'blue',
					window: w1
				});

			w1.add(b1);
			b1.addEventListener('click', function(e){
				t.close();
			});
			t.addTab(t1);	
			t.open();
		}
	});

	optDlg.show();
	Ti.API.info('must be showing dlg');
});

w.add(b);
w.open();
