You are not able to directly change the value of an object property, this is one caveat of using custom properties. Take for example:

   // app.js
   mywindow.userInfo = {      
     id:  1,
     name: 'John Doe',
     location: 'Neverland'
   };
   mywindow.userInfo.location = "Wonderland";
   
   alert(mywindow.userInfo.location); // still "Neverland"

You cannot directly change the location value. In order to change it you must do:

   var userInfo = mywindow.userInfo;
   userInfo.location = "Wonderland";
   mywindow.userInfo = userInfo; // set the whole modified again
   
   alert(mywindow.userInfo.location); // now "Wonderland" 
   alert(mywindow.userInfo.name); // other properties still work

for more information please take a look at this page: http://shikii.net/blog/custom-properties-in-titanium-windows-and-controls/ If you have any more questions, feel free to ask. Regards, Carter

Ok, thanks for the quick response. The behavior of the custom properties is a bit strange. I found this solution to give/set references: // app.js var userInfo = { id: 1, name: 'John Doe', location: 'Neverland' }; mywindow.getUserInfo = function() { return userInfo; } mywindow.setUserInfo = function(property, value) { userInfo[property] = value; } userInfo.location = "Wonderland"; alert(mywindow.getUserInfo().location); // "Wonderland" Regards Jacek
