Mapping Object using a script.

I use the Mapping Objects sample code in this link:  http://support.smartbear.com/viewarticle/57311/

But I have a problem here, as I've trace the "MappedObj" variable, only the first child item is mapped properly the succeeding item is not.

Is it a bug or did I missed something? I used the JavaScript sample code in my WPF application.

I need this feature because my software requirement has a bunch of buttons with identical functionality to boost my creation of test case.

Thank you.
