Adding SubHeader to Fiori Launchpad

Hello,

I'm trying to add a custom SubHeader to the Fiori Launchpad, as referenced in:

Adding a Sub Header - SAP Fiori Launchpad - SAP Library

I've added the code from the example to the FioriLaunchpad.html at what I thought was the correct line for this.

However, when I run this, I get an error in the Chrome console saying:

2016-01-15 10:25:57 Call to success handler failed: sap.ushell.Container.getRenderer is not a function - TypeError: sap.ushell.Container.getRenderer is not a function

    at main

Does anyone know how to add a custom sub header successfully?

Thanks and regards

Patrick
