AppBuilder - Back button

Hi guys, Hi Pavel, Hi Midhun,

I'm having a problem with the "Back" button.

It's there because on each page I've activated the "showNavButton" option.But the thing is ... it doesn't work, nothing happens.

I didn't modify the default function "backBtnTap: function() ":

backBtnTap: function() {

     var bus = sap.ui.getCore().getEventBus();

     bus.publish("nav", "back");

},

Anyone has a clue?

Thanks,

Marius.
