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) {
}
};
