Version: Extjs 4.0 beta release
Infinite Scrolling Example


enabled row selection in example by changing the property on line 68 from
disableSelection: true to disableSelection: false

Steps to reproduce:
1. Select row 4
2. Scroll down to row 300
3. Scroll back to row 1

Selection is gone. (Row 4 should still be select since I have not selected any other row while scrolling)
