How to preload for Windows in tabs


I need to preload all the windows in the tabgroup. I read on this forum that createWindow can be passed 'preload: true' but that is not working.

var contactsWindow = Titanium.UI.createWindow({  
    preload: true    

My app.js raises an event (after doing a webservice) which I use to initialize the windows in the various tabs of tabgroup. If the windows are not initialized then I believe the event is being ignored and they do not initialize.

How can I solve this issue?

    That's true, you won't be able to preload windows assigned to tabs. What you can do is in contacts_window.js fire an event asking for the data you need.

    In app.js:

    // this is the data needed by the other windows
    var webServiceResults = null;
    // ...
    // call web service and store results in variable above
    // ...
    Ti.App.addEventListener("getData", function() {
      Ti.App.fireEvent("sendData", {

    and in contacts_window.js or any other tab:

    Ti.App.addEventListener("sendData", function(e) {
      // e.myResult contains the result of your web service

    So in this model, your tab asks for the data it needs when it loads, using custom events.
