Changing views using ListBoxes

Hi!

I'm trying to create an application using the view architecture. I've 2 different views, each one being a Listbox implementation.
I've set their containers classes to the be the Listbox observers.
What I want to do is use a listbox option in the first one to change to the second listbox (the other view) but I can´t get a way to pass the events from the container to the AppUi.

Something like this in the first view container:

void CviewTestContainer::HandleListBoxEventL(CEikListBox* aListBox, TListBoxEvent aListBoxEvent)
   {
   // if the Select Key has been pressed
      if (aListBoxEvent == MEikListBoxObserver::EEventEnterKeyPressed)
      {
         TInt index = aListBox->CurrentItemIndex();
         if (index == 0)
            // Call something in the AppUi that changes the view and creates the listbox according to the option selected
         if (index == 1)
                // Create another listbox
      }
   }

Does anybody have any idea how it can be done?

Thanks

Sergio
