Description

1. Run this code

var win = Ti.UI.createWindow({
    backgroundColor: 'white'
});
 
function onPropertiesChange()
{
   
    Ti.API.info('change fired')
    Ti.App.Properties.setBool('test', true);
    Ti.App.Properties.setDouble('test1', 2.5);
    Ti.App.Properties.setInt('test2', 45);
    Ti.App.Properties.setString('test3', "hello");
}
     
Ti.App.Properties.addEventListener('change',onPropertiesChange);

Ti.App.Properties.setBool('test', true);
Ti.App.Properties.setDouble('test1', 2.5);
Ti.App.Properties.setInt('test2', 45);
Ti.App.Properties.setString('test3', "hello");
  
win.open();

2. Look at log and observe infinite loop. On Android, "change" is only called 4 times. Expected Behavior: - "change" should only be called 5 times - since iOS also adds appGUID when launching the app for the first time.

The change is fired 4 times on Android and 5 times on iOS. Verified on: Titanium Studio: 3.0.0.201211301903 Titanium SDK:3.0.0.v20121204181658 Device: Nexus 7 (Android v4.1), iOS Simulator (v6.0), iPad2 (v5.1) XCode: 4.5.1
