I was creating a skin today and I need to be able to create children within the skin and add them to it’s display list. This wasn’t possible when extending Border or ProgrammaticSkin as they are not DisplayObjectContainers, they extend FlexShape (i.e. a DisplayObject).
I came across this post where Ely suggested creating some base classes that have this functionality (i.e. extend FlexSprite), so here they for anyone else who needs them.
