Lists JavaScript

[freal...@gmail.com]

Hi Team.
I have some lists created inside my web interface.
I have something like this:

var mylist =id_supplier.getSelectedLabel();
var temp = new Array();
var a = new RMP_List();
if( mylist== "XPTO")
{
temp.push({"label":"Software","value":"software"});
a.fromArray(temp);
RMPApplication.setList("array.vb_list",a);
}

I want to know, if there if is it possible to do this in one collection and if it works fine too, or the unique way is how I created, with JavaScript.
