I am trying to take the recommendation from the Adobe code hints and use spark containers rather than halo, but I had a <mx:Canvas> as a module holder and was playing an effect (Iris) on it before the module displayed. Now I am getting an error.
I check the Adobe Flex 4 Notes (Available Effects) and see there is no equal for Iris in Spark. So I cannot use that effect on a VGroup at all or is there some other way to get that effect? Not 100% committed to it, just liked it for the type of application I am creating. Thanks!
