Hi Gordon, I've been using Canvas with ViewStack too. The reason is that I don't know of a lower level alternative that extends Container. I would have thought UIComponent was a good option as it does have Container as a sub-class but I get type coercion error failed to convert to mx.core.containers. What is a good container to extend?
