Simply run the example ..\examples\grid\infinite-scroll.html,

If set the return data 'totalCount' to a vary large num ,like 600000,

and drag the scroll bar to the bottom, you can see the index of data only 537xx,

that mean their a lost of data can not show in the grid.

This debug only in IE8 ,

the others browser like IE6,chrome,Firfox is OK ,they can see the data index to 600000

In my test ,I only change the store url to a json file (in server)

this is my test code
