  there's no direct way to reload the app.js or main application context.

  to probably do what you're talking, you'd want to put everything in a new window which is a separate JS context (vs. app.js) and then reload that window.

  your window could simply be a non-visual window that opens other windows, tabs, etc. but could then be used to reload (by closing and re-opening) on a language change.

• maybe you can do this with a little trick by using Titanium.App which is available in the whole app:

  var language = Titanium.Platform.locale;
  Titanium.App.Properties.setString('locale',language);
  Titanium.App.language = language;
  

  when calling your language files simply use:

  var language = Titanium.App.language;
  

  so you have the setting saved for the next run of the app and also available for actual run.

  hope that helps.

• Exactly what do you mean with
  "which is a separate JS context (vs. app.js) and then reload that window."
  ?

• In your app.js, create a new window to another file:

  function reopen()
  {
    var window = Ti.UI.createWindow({url:"myapp.js"});  
    window.open();
  }
  reopen();
  
  Ti.App.addEventListener('reload',reopen);
  

  Then in myapp.js when you want to reload the app, call

  Ti.App.fireEvent('reload');
