[flexcoders] Best Way To Implement tabnavigator switching

[iilsley]

I have a Tabnavigator with 3 customer components ..

Each component has a 'getData' method which loads the data for that
component .

I currently have a change event handler on the tabnavigator
which does a

             private function changeView(e:IndexChangedEvent):void
             {
                 var o:Object = e.relatedObject;
                 o.getData();
             }

This works but is this the 'correct' way todo it ?
