Hi Patrick,

For nested binding, you have to use a manual binding in the inner binding. So here are the steps:

• For the outer binding (in your case, the tabs), you can use the data source feature to configure the source of your binding (e.g., business object or global variable)
• For the inner binding (in your case, the list inside a tab), you have to use a manual binding:
• Click on the list and search for ‘items’. Next to the property ‘itemsPath’, click on the binding icon and select ‘Manual’. Then, enter the binding in the form ‘Screenname>SubCollectionName’ (without any brackets, as this is a string value). Set the property ‘itemsTemplate’ to true
• For the widgets inside the list items, you also have to use a manual binding: Click on the binding icon next to the property that you want to bind. Select ‘Manual’. Then, enter the binding in the form ‘{Screenname>SubCollectionPropertyName}’
• If you are using a global variable as the data source, use ‘variableHolder’ instead of the screen name in the manual binding

Let me know if you have any further questions.
