Hi Sebastian,

I am trying to apply the quick start to the real project.
I have the problem that the onSuccess method is not called  - in the quickStart it works.
Do you know a hint but it is of course hard to figure it out from the distance.

br Chris

final Future<List<Route>> contentsFuture = routeGenerateService.generateRoutes();

            FutureUpdateBehaviour<List<Route>> futureUpdateBehaviour = new FutureUpdateBehaviour<List<Route>>(Duration.seconds(2),
contentsFuture) {
                @Override
                protected void onPostSuccess(AjaxRequestTarget target) {
                    System.out.println("Success");

                    routingListPanel.setVisible(true);
                    target.add(routingListPanel.getParent());

                }

                @Override
                protected void onUpdateError(AjaxRequestTarget target, Exception e) {

                }
            };
