PageMap in wicket 6.x or 7.x

I am trying to convert below code into wicket 6.x, But I am unable to find some required methods, does anybody have any solution for this?

  PopupSettings popupSettings = new PopupSettings(PageMap.forName("popuppagemap"), PopupSettings.SCROLLBARS).setHeight(500).setWidth(700);

Solution

You dont need a PageMap You can send only string :

PopupSettings popupSettings = new PopupSettings("popuppagemap", PopupSettings.SCROLLBARS).setHeight(500).setWidth(700);
