Titanium appcelerator: Passing reference in other Windows

I am using multiple window apps being controlle via Tabgroup. I am using .js files for each window which are passed as URL with each window. I also have a function.js file where I am writing routines for reusable code;for instance Form generation or table View etc. Now I got stuck in a situation where I have to call a function which generates form element which are in WindowA. In WindowA I explicitly defined all required form elements. Now what do I pass in my function routine that it gets the reference of already created form element.

Please note that TableView created in separate Window, say WinB and I am generating rows by calling a routine written in functions.js. Ia m getting undefined error despite of variables are global in WinA.

How can I get the reference of those variables in entire application?

I highly recommend NOT using Ti.App to pass variables - even if it works. It is not best practice. I know you won't want to, but Take the time refactoring your code to not use windows with urls - go to a single instance / commonJS approach.

See https://wiki.appcelerator.org/display/guides/Mobile+Best+Practices and https://wiki.appcelerator.org/display/guides/CommonJS+Modules+in+Titanium

Also see https://github.com/appcelerator-titans/App for current best practice code.

It will take a while to refactor, but you app will be much more stable, and your code will be much cleaner.

First of all you can declare global variable in e.g. Ti.App object. AFAIR, this or some similar thing didn't work properly on iPhone.

If this will not work, there's a trick with closure:

myVar = {field: 'some value'};
Ti.App.getMyGlobalVar = function() {
    return myVar;
}

Also, I'm not sure whether Ti.App or some other namespace will work. It has been several months, since I used Titanium appcelerator.
