The parentApplication property is a reference to the Application
object (the nesting refers to applications loaded within other
applications with the Loader control and probably doesn't apply to
your case), but it's a property of mx.core.UIObject, which your
SDMDelegate obviously isn't extending and probably shouldn't. Have
you tried dumping mx.core.Application.application.myServices in the
delegate constructor to see if it exists at that point? You could
also try adding a creationComplete event to the application to
determine exactly when the siteDataServices remote object is
available; something like
creationComplete="Dumper.dump(myServices.siteDataServices)" should do it.
It might be your best bet to pass the service to your delegate
constructor as a parameter.
