hi All

This is my first post on this forum , just started the BB 10 development and also C ++ as I am a Java Person.
I am having some problem in QML and C++ intergration

Here what I am trying to do:

I have login page , on login button click my new page (which is a navigation pane ) gets open without any issue
here is the method I use

void Integration:penNextPage() {
printLog("-- open second page (a navigation pane ");
new SecondPageHndlr (appRefrence);
}

here is what I am doing in SecondPageHndlr class :
SecondPageHndlr.cpp

Code:
#include "SecondPageHndlr.hpp"
#include "ThirdPageHndlr.hpp"


#include <bb/cascades/Application>
#include <bb/cascades/QmlDocument>
#include <bb/cascades/AbstractPane>
#include <bb/cascades/NavigationPane>
#include <bb/cascades/Page>
#include <bb/cascades/Sheet>


#include <QObject>
#include <QIODevice>


#include <iostream.h>
#include <string.h>
#include <stdio.h>


using namespace bb::cascades;


SecondPageHndlr::SecondPageHndlr(bb::cascades::Application *app)
: QObject(app){
    try{
            QmlDocument *secondQml = QmlDocument::create("asset:///SecondPage.qml");
            if (!secondQml->hasErrors()) {


                NavigationPane* page = secondQml->createRootObject<NavigationPane>();


                if (page)
                {
                    printLog("second page view . page is not  null ");


                    //make this c++ file accessable from the dashboardviewn.qml


                    pane = page;


                    secondQml->setContextProperty("second", this );


                    app->setScene(page);


                }
                else
                    printLog("page is null ");


            }
            else
                printLog("Error in second page view QML");
        }
        catch (std::exception& e)
        {
            printLog("-------- Exception");
            std::cout << "Exception: " << e.what();
        }
}


void SecondPageHndlr::showThirdScreen(){
    printLog("-- open Third page (a navigation pane pushes a new page");
    new ThirdPageHndlr (pane);
}


void SecondPageHndlr::printLog(const char *str){
    cout <<"\n" << str ;
    printf("" ,1);
    fflush(stdout);
}
Now when from this second screen I try to open the third page it would not work at all
kindly see the code and tell me what em doing wrong

Regards
