Moin Ede :) I want to do it in my plugin, not via scripting. I had no idea that scripting was possible though, thanks!
I did add context.getLayerViewPanel().repaint(); as last line now, nothing visually changed. I attached an image, not sure if it will work on this mailing list. Alternatively it is at http://i.imgur.com/tbPOGft.png Layer#fireAppearanceChanged says "This event will be ignored if LayerManager#isFiringEvents is false". I checked and context.getLayerManager().isFiringEvents() is true. To me the documentation of Layer#fireAppearanceChanged suggests it is all that is needed.
