[Seaside] #onScroll: with positions

[Dennis Schetinin]

Hello, seasiders!

We would like to implement a GoogleReader-like table component which
loads additional data to the table while scrolling down to (or near)
the bottom. We tried #onScroll: event but it does not include position
parameters for scroller. The possible decision is to implement a
client-side script posting those parameters, but we are not sure how
to do it in practice.
Can anybody help us with it or maybe offer a better (simpler) solution
for original task?
Thanks in advance.
