如何使用自定义应用程序中的后退按钮访问 Fiori Launchpad？

Question

I am not able to get the back button in my custom Fiori-like app to work. I have added my app to the Fiori Launchpad and tried following code in the press-event:

var oCrossAppNavigator = sap.ushell.Container
            .getService("CrossApplicationNavigation");
    oCrossAppNavigator.toExternal({
        target : {
            semanticObject : "#"
        }
    });

This is not working for me. I know there is a Home button but I would like my app to behave like the standard Fiori apps.

Following code works but feels like some sort of dirty hack to me:

window.history.go(-1);

Installed UI5-Version is 1.28.8

Thanks for your help! :)

You can make it work by using the shellHash property instead of semanticObject :

sap.ushell.Container.getService("CrossApplicationNavigation").toExternal({
    target: {
        shellHash: "#"
    }
});
