AbstractAjaxTimerBehavior causes exception

[Giambalvo, Christian]

Hi all,

 

maybe i found a bug.

Don't know if I'm doing something wrong.

But it's a simple usecase.

 

Following code produces an exception:

 

public class HomePage extends WebPage {

 

    private static final long serialVersionUID = 1L;

 

    private static int testCounter = 0;

 

    public HomePage(final PageParameters parameters) {

 

        // Add the simplest type of label

        final Label test = new Label("message", "If you see this message
wicket is properly configured and running");

        test.add(new AbstractAjaxTimerBehavior(Duration.seconds(1))

        {

            @Override

            protected void onTimer(AjaxRequestTarget target) 

            {

                Label t2 = new Label("message", "Test " + testCounter);

                test.replaceWith(t2);

                testCounter++;

                target.addComponent(test);

            }

        });

 

        add(test);

    }

}

 

Exception:
