You can replace "Main.map.mapView.addMouseListener(mouseAdapter);" with
"MainApplication.getMap().mapView.addMouseListener(mouseAdapter);".

The comment in MapFrame.java is misleading: use of the field mapView is 
only discouraged for accessing methods the have been moved from MapView 
to LayerManager.

You don't normally need the MainPanel instance, but it can be accessed 
with MainApplication.getMainPanel().
