Can you share the code snippet from TopNav.java ?

HI Dubey

Thanks for responding

Please find the below code snipplet.

//package apps.training.components.site-topnav

import java.util.*;

import java.util.Iterator;

import com.day.cq.wcm.api.*;

import com.day.cq.sightly.WCMUsePojo;

public class TopNav extends WCMUsePojo

{

private List<Page> items=new ArrayList<Page>();

private Page rootPage;

@Override   

    public void activate() throws Exception{

   rootPage=currentPage.getAbsoluteParent(2);

        if(rootPage==null)

        {

            rootPage=getCurrentPage();

        }

        Iterator<Page>  childPages=rootPage.listChildren(new PageFilter(getRequest()));

        while(childPages.hasNext())

        {

items.add(childPages.next());

        }

    }

    public List<Page> getItems()

    {

return items;

    }

    public Page getPage()

    {

return rootPage;

    }

}

Thanks for your explanation!!. It helped me a lot.
