I have a Detail view in an SAPUI5 app which contains a single input field with ID \"bestellmenge_tu\". Whenever this view is called, the focus should be on that
The NavContainer has a property autoFocus. App is a descendant of NavContainer so it has that property too.
The help (as linked above) states the following:
Determines whether the initial focus is set automatically on first rendering and after navigating to a new page. This is useful when on touch devices the keyboard pops out due to the focus being automatically set on an input field. If necessary the "afterShow" event can be used to focus another element.
Default value is true.
