Description

Steps to reproduce:
1. Please find the code and direction to reproduce inside the attached example.

In general, after List's dataProvider is completely replaced, the List isn't populated properly (or isn't populated at all). The NPE happens when attempting to scroll the List after it's been unsuccessfully populated second time.

Workaround (if any):
For now, the only workaround is to remove the List component and add it once again, when you need to reload the data. The workaround is costy in terms of performance.
