It is tricky to reproduce.

The issue is shown on the attached movie. I set many pages. And I set 5 items in indicators.

I navigate scrollbar of unidirectional binding to 49 (approximately, maybe, a few attempts are needed). and call set. That is - standart setCurrentPageIndex(int) method of pagination API will be called. and I am navigated to page content 49. And page indeces starting from 51.

That looks like +\-1 problem.

If I click left, you see, that not the most right item is selected as index. That shows, that incorrect range was shown.
