Wicket way:
final IModel>> listPerGroup =
LoadableDetachableModel.of(() -> reportService.listPerGroup());
add(new ListView("group", () -> new
ArrayList<>(listPerGroup.getObject().keySet())) {
@Override
protected void populateItem(ListItem groupItem) {
yes, thank you, that's the reason! The problem is the Comparator in TreeMap.
I prefer to use your second proposed solution, however my service returns
Map> and I render the result in two nested ListView as
follows:
final Map> listPerGroup =
reportService.listPerGroup();
Hi,
your service method is return a TreeMap holding a lambda comparator:
Comparator.comparing(DataGroup::getName)
Either you make that comparator serializable (you can but you don't *need* to
use org.danekja as Wicket does it):

That's strange. Could you show the full exception stack trace?

I manually create the Spring context, which is ClassPathXmlApplicationContext,
and pass it to Wicket application by calling
getComponentInstantiationListeners().add(new SpringComponentInjector(this,
MyApp.get().getApplicationContext())).
Then, In my panel I have this
private class Rep
I think you are keeping a reference to your Spring bean in a page or in a
component, that's why Wicket is trying to serialize it. Are you injecting
this bean with @SpringBean annotation?

Thanks for your reply.
Both of your proposed solutions mean using other interfaces in the Lambda
expressions. However most of my Lambda definitions are in my Service tier
classes (Spring beans), and the Service tier must be independent from the Web
tier, and the force of Wicket serialization (e

Hi,
I'm using Apache Wicket 7.9.0 alongside Spring 5.0.5.RELEASE. In one of my
beans, I call some stream API containing multiple lambda expressions. During
that page execution, I get following exception:
Caused by: java.io.NotSerializableException:
org.devocative.metis.service.data.ReportServi
