This is because your page are stateful, Wicket manages its own states to your page by appending this "counter". This way, when your user navigate backward using its browser built-in functionnality, the page is displayed has it has been previously.

If you don't want such a parameter in your URL, you'll need to dig out and eradicate every stateful component in your pages.

Thank you, how can I sole this? params.add("link", components.getModelObject().getPermalink()); params.add("code", code); Link link = new BookmarkablePageLink("link", OrderPage.class, params); link.add(new Label("linksel", "Select")); components.add(link); I am just click on url and second page extended BasePage – Armen Arzumanyan Apr 06 '13 at 21:52
You can help Wicket by defining `getStatelessHint()` returning true in your base page. I'm afraid you'll need to fire the debugger in order to find which component is stateful in order to suppress this in your url. – Cedric Gatay Apr 06 '13 at 22:05
How we can remove that counter from url? – Armen Arzumanyan Apr 09 '13 at 14:59

You can create

public class MountedMapperWithoutPageComponentInfo extends MountedMapper {

public MountedMapperWithoutPageComponentInfo(String mountPath, Class<? extends IRequestablePage> pageClass) {
    super(mountPath, pageClass, new PageParametersEncoder());
}

@Override
protected void encodePageComponentInfo(Url url, PageComponentInfo info) {

}

@Override
public Url mapHandler(IRequestHandler requestHandler) {
    if (requestHandler instanceof ListenerInterfaceRequestHandler) {
        return null;
    } else {
        return super.mapHandler(requestHandler);
    }
}

}

and map page on Application class like this

mount(new MountedMapperWithoutPageComponentInfo("/page/#{code}/#{name}", Page.class));
