Hi Olivier, I simple way to achieve this is to have a (abstract) #onError method:
public abstract class MyModel extends LoadableDetachableModel<List<MyObject>> { private static final long serialVersionUID = 1L; private static final Logger LOG = LoggerFactory.getLogger(DashboardModel.class); public MyModel() { } @Override protected List<MyObject> load() { List<MyObject> list = new ArrayList<MyObject>(); try { //TODO fill list; } catch (TheException e) { this.error(e.getMessage(), e); } return list; } private void error(String message, Exception e) { LOG.error(message, e); this.onError(message); } protected abstract void onError(String message); } In MyPage private MyModel newMyModel() { return new MyModel() { private static final long serialVersionUID = 1L; @Override protected void onError(String message) { MyPage.this.error(message); } }; } Hope this helps, Sebastien.
