ProgressBar.setValue(..) takes a Float between 0 and 1 as a parameter. (See: https://vaadin.com/download/release/8.4/8.4.1/docs/api/com/vaadin/ui/ProgressBar.html#setValue-float- )

This means that you need to scale your value to this range, say value = index / total If the index is Integer between 0 and total.
