Cool; let me look for a moment:
public void setStyle(Style style) {
this.style = style;
}
Yep; no event in sight! My understanding is we should add the following:
fireMapLayerListenerLayerChanged( MapLayerEvent.STYLE_CHANGED )
(the method is nice and efficient and only bothers to do something if there is
somebody listening)
Aside; I went looking for docs and did not find any; thus you have the
following notes* I have just added to the user guide:

* notes in this case means I missed something; and had to go make diagrams and
stuff
