Model is compile time object, which means you can only mention source on
compile time. If you want to load different XML on runtime, you should use
HTTPService instead. What I understand from your code is, you are loading an
xml into a Model and binding Model to MenuBar's dataProvider.
Following is a quick example, that allows to load two different xml data for
MenuBar. You can see, how HTTPService is able to load xml files on runtime
and result is bound to MenuBar dataProvider.
You can find the attached file, place in flex application directory and run
the HTTPServiceExample.mxml.
1) ##HTTPServiceExample.mxml##
?xml version=1.0 encoding=iso-8859-1?
mx:Application width=800 height=600
xmlns:mx=http://www.macromedia.com/2003/mxml;
mx:Script
![CDATA[
function loadMenudata1()
{
service.url = menudata1.xml;
service.send();
}
function loadMenudata2()
{
service.url = menudata2.xml;
service.send();
}
]]
/mx:Script
mx:HTTPService id=service resultFormat=object url=
useProxy=false/mx:HTTPService
mx:MenuBar dataProvider={service.result}/mx:MenuBar
mx:Button label=load menudata1 click=loadMenudata1()/
mx:Button label=load menudata2 click=loadMenudata2()/
/mx:Application
2) ##menudata1.xml##
menuitem label=MenuItem A
menuitem label=SubMenuItem 1-A /
menuitem label=SubMenuItem 2-A /
/menuitem
3) ##menudata2.xml##
menuitem label=MenuItem B
menuitem label=SubMenuItem 1-B /
menuitem label=SubMenuItem 2-B /
/menuitem

Sorry for not answering sooner. You should look into using the
HTTPService instead of a Model in this case. HTTPService can decode XML
into an object structure but does it dynamically instead of statically like
the Model does.
