I am getting NPE whenever I am invalidating session. Below is my code

    System.out.println("Executions.getCurrent():"+Executions.getCurrent()); //Not null 


    ServletContext context = Sessions.getCurrent().getWebApp().getServletContext();
    Map<String,HttpSession> multipleSessionMap = new HashMap<String,HttpSession>();
    // code for putting session in map
        HttpSession httpSession=multipleSessionMap.get("session");
        httpSession.invalidate();
        System.out.println("Executions.getCurrent() :"+Executions.getCurrent()); //returns null
        Executions.sendRedirect("/success.zul");

I am getting Execution.getCurrent() before session invalidate call but after it sets to null.

Thanks for the help in advance.. Any help would be appreciated.

Hello

I will suggest you to read through below link's as they will give you more clear understanding about cleanups http://books.zkoss.org/wiki/ZKDeveloper'sReference/Customization/InitandCleanup

prefer using SessionCleanup to do your session cleaning http://www.zkoss.org/javadoc/latest/zk/org/zkoss/zk/ui/util/SessionCleanup.html
