Thanks jody, that gets me further. Now comes the tricky bit. The current SelectionLab example implicitly relies on the do-everything nature of JMapPane.paintComponent.
In my local "improved" JMapPane the paintComponent method's only job is to blit the backing image to the pane. The actual map drawing has been moved into a separate method and the map pane relies on events from its MapContext to know when that needs updating. For this to work I need FeatureLayer.setStyle to publish an event. Michael PS. Perhaps I should commit the GEOT-3560 changes to trunk so we are both looking at the same code ?
