title: Flex Viewstack's children, if you can't see them, do they exist?
body: <p>I seem to be running into an issue (Cannot access a property or method of a null object reference) binding events in actionscript to a viewstack layer not currently showing. Are those objects not created until that layer is visible for the first time? I remember something about a creation policy, if this is the case, can I force it to create those children before that layer is viewed?</p>
