Superlist Navigation Issue in AppBuilder

[Former Member]

Hi All,

  I did the AppBuilder superlist appilcation from this reference AppBuilder: Create the Northwind App with a SuperList component - YouTube

It is showing the data in list view, when i clicked on particular item it is navigating to the details view of that particular item.

Now I am unable to get back from the details view to Main list view.

for that I wrote the follwing code, but it does not effect the application

backButtonTap: function(evt) {

  var oCore = sap.ui.getCore();

  var sl = this.byId("SuperList1");

  var page = oCore.byId("appView").byId("HomePageView").byId("HomePage");

  sl.drillBack();

  if (sl.getCurrentLevel()===0){

  page.setTitle("SapData");

   page.setShowNavButton(false);

   }

   else {

  page.setShowNavButton(true);

  }

},

myRowFocusChanged: function(evt) {

var oCore = sap.ui.getCore();

  var sl = this.byId("SuperList1");

  var page = oCore.byId("appView").byId("HomePageView").byId("HomePage");

  var data = sl.getRow(evt.mParameters.row);

  var title = data[0];

  sl.drillDown(evt.mParameters.row);

  if (sl.getCurrentLevel()>0){

  page.setTitle(title);

   page.setShowNavButton(true);

  }

}

Is any issue with my code?

Thanks,

Hi sravanya,

can you mention the code in btn-onTap function .

also can you try removing var oCore = sap.ui.getCore();  in function(evt) changing

if (sl.getCurrentLevel()===0){

to

if (sl.getCurrentLevel()==0){

regards

Sravnaya,

There was a similar issue in page navigation at and was resolved with the below code . please check if it might work.

backButtonTap: function(evt) {
		try
		{var s1 = this.byId("SuperList1");

        var page = sap.ui.getCore().byId("appView").byId("homePageView").byId("homePage");

        s1.drillBack();

        if (s1.getCurrentLevel()===0){

            page.setTitle("Northwind Sample");

page.setShowNavButton(false);

        }

        else {

            appView.setShowNavButton(true);

        }

			}catch(e)
				{
					alert(e);
				}
	},

	myRowFocusChanged: function(evt) {
	try{
		var s1 = this.byId("SuperList1");

        var page = sap.ui.getCore().byId("appView").byId("homePageView").byId("homePage");

        // alert('test1');

        var data = s1.getRow(evt.mParameters.row);

        // alert('test2');

var title = data[4]+ ' ' +data[2]+ ' ' +data[1];

        // alert('test3');

        s1.drillDown(evt.mParameters.row);

        if (s1.getCurrentLevel()>0){

// alert('test4' + title);

            page.setTitle(title);

              // alert('test5');

            page.setShowNavButton(true);

        }

	}catch(e){
			alert(e);
	}
	}
