Hi,

I am trying to combine selection library with paging library. Loading items from paging library works ok, but when I try to select item with long click (or with long click and dragging to select more items), the app crash:

java.lang.IllegalStateException: Range start point not set.

...

When you pre-load some pages with scrolling the RecyclerView, it crash after selecting more items with dragging. See attached videos.

Sample code attached.

Library versions:
RecyclerView: 1.0.0
RecyclerView Selection:1.0.0
Paging: 2.1.0
