sap - Split app in ui5 the back button doesnot work -

i tried implement split app feature in mobile application .but after navigating detail2 page "back" navigation button put , not work when pressed . have placed code below : (revert if need more info on that) view.js file (content) :

sap.ui.jsview("split_app.first_view", {     getcontrollername : function() {         return "split_app.first_view";     },       createcontent : function(ocontroller) {           var olist1 = new sap.m.standardlistitem({             type: sap.m.listtype.active,             title: "to detail 1",             tap: function(){                     osplit.todetail("detail1");                 }         });         var olist2 = new sap.m.standardlistitem({             type: sap.m.listtype.active,             title: "to detail 2",             tap: function(){                     osplit.todetail("detail2");                 }         });          var otext = new sap.m.label({             text: "first label",         });          var osplit = new sap.m.splitapp("split");          var odetail1 = new sap.m.page("detail1", {             title: "first details",             content: [                         otext                       ]         });         var odetail2 = new sap.m.page("detail2",{             title: "second details",             shownavbutton: true,             navbuttonpress: function(){                 osplit.tomaster("masterpage");                               app.back();             },              content: [                       new sap.m.label({                           text: "second label"                       })                       ]         });          var omaster1 = new sap.m.page("masterpage", {             title: "master page",             content:[                       new sap.m.list({                            items : [ olist1, olist2 ]                       }) ]         });          osplit.addmasterpage(omaster1);         osplit.adddetailpage(odetail1).adddetailpage(odetail2);         osplit.setmode("showhidemode");          return new sap.m.page({             title: "title",             content: [                     osplit               ]         });     } 

assuming want navigate 1 step in detail area (right side) can call backdetail() function of splitapp object when clicking on button (navbuttonpress):

osplit.backdetail(); 

the same function works navigation in master area (left side):

osplit.backmaster(); 

if want navigate within app object, make sure there previous page come , pages known app object (probably in index.html file): i´ve tested code , worked me navigate within splitapp using above mentioned functions navigating in app following declaration (in index or wherever host app object):

var app = new sap.m.app();  var init = sap.ui.view({     id : "idinit",     viewname : "stackovertest.init",     type : sap.ui.core.mvc.viewtype.js })  var page = sap.ui.view({     id : "idsplit_app1",     viewname : "stackovertest.split_app",     type : sap.ui.core.mvc.viewtype.js }); app.addpage(init); app.addpage(page); 

after coming init page can use

app.back(); 

hopefully helps you.
