JavaFX 1.2, ListView, is it possible to have an event when an item is sel?

Question

I have a listview, in it contains a lot of text in the format of "abcd -> efgh". When the user selects any item in the ListView, I need two textboxes to populate, one with "abcd" and the other with "efgh". Any thoughts?
I'm using NetBeans6.8 and JavaFX 1.2. Moving to 1.3 is not an option, so let me know if this can be done :)
Thanks!

Now I guess I'm still confused on one thing. Where should this code go exactly? I wrote the following:
        //Bind the selected index of the Component Catalog in order to populate the textboxes
        var compCatalogSelectedIndex = bind compCatalogListView.selectedItem on replace {
            def myItem = compCatalogSelectedIndex as String;
            var separator = "->";
            var mapping:String[] = myItem.split(separator);
            //Set component side
            componentTextBox.text = mapping[0];
            //Set catalog side
            catalogTextBox.text = mapping[1];
        }I threw a breakpoint in there and it's not reaching it when I change the index.
