Scenes and Combobox

Hi
I have a XML connector and a Combobox. I read a xml file and the combobox
show me the xml file.
I use the following code
ds = new Object();
ds.result = function(ev) {
_root.alfredo.refreshDestinations();
}
alfredo.addEventListener(“result”,ds);
alfredo.trigger();
After i create a Binding for the combobox and everyting works fine.
It works fine when i have one scene. If i have more than one scene it doesnt
work. Please anybody know why?
Thanks
Mario
