When a Skin is set on a Control that is an anonymous inner class and setStyle is called, I will get the following log:

SEVERE: No valid constructor defined in 'hs.javafx.demo.ControlPanel$1$1' for control Carousel@1a20941[styleClass=carousel].
You must provide a constructor that accepts a single Skinnable (e.g. Control or PopupControl) parameter in hs.javafx.demo.ControlPanel$1$1.

I don't see why this is occuring as I specifically already instantiated this Skin (in a factory), using the following code:

  new CircularRayCarouselSkin(skinnable) {
    @Override
    protected void postLayoutCustomizeCell(RayLayoutItem item) {
       // Customization code
    }
  };

This makes Skins needlessly complex to switch and customize -- also see the discussion titled "Future of Skins" on the openjfx dev mailinglist.
