I'm using excludeIn and includeIn with states to show/hide certain elements. What's the best practice of knowing hidden elements become available? I frequently change to a new state and set labels/dataproviders/etc. on the elements in that state. Databinding isn't always a clean solution. Right now I just have a creationComplete handler for a group that contains the changing items, but obviously this won't work if I have numerous elements spread all over the interface.
