[Seaside] scroll position between two states

[Luc Damas]

Hi,

Imagine you have a page displaying 2000 lines (hum!). Each line contains 
a remove button.
Example of the problem:
On the screen, I can see lines from 1300 to 1400.
I want to delete line #1347.
It works (very easy!), but the page is displayed at its beginning. I now 
see lines from 1 to 100, and I would like see lines from 1300 to 1400, 
as before clicking on the remove button!

How can I preserve the page scrolling between two states of a component?

thanks
