I had a combo and grid on page.
Combo has two values: value 1 with 372 items and value 2 with 21 items.
grid has paging enabled with pagesize 20 and serveroperation false.

Now when i select value 1 in combo then all 372 items are displayed in grid and then i go to 6th page of grids paging at this time in grids paging it is shown "101 - 120 items of 372 items"and then if i select value 2 in combo then no items are displayed in grid but paging shows "101 - 21 of 21 items" because it is yet on page 6 but this time there is no page 6 and in controller the request shows page 1. This is a bug.

Regards,
