That is an interesting use case. Can you describe it a bit more?

My app works more like a browser, so when I "go back", I expect the same screen
layout again (even though I have to reconstruct the screen again). With a ListView, this
cannot be done as the #scrollTo method only shows an item. It doesn't remember however
if that item was somewhere in the middle, top or bottom. It's just convenient if it was
in the same spot, as the user might expect it there. Just like I expect my browser to go
back to the same spot helps me a bit (eg: I clicked the link at the bottom of the screen
somewhere, and there was something else interesting to the left of it -- that fails if it
is now somewhere else).
Ah, ok. So I am curious; even though the browser main scrollbar might return to
the position you were before (or even when refreshing a site might do), will it
also return divs-with-scrollbar to the same position? I doubt it.
But HTML is much more low level than JavaFX's controls; if you were to build a
JavaFX screen just using primitive controls, so create your own list with a
pane and a scrollbar, then that scrollbar's API is available and you can do
what you want. As soon as you start encapsulating things, then it becomes more
interesting. Does for example JSF's list control allow you to specify the
scroll position, or JQuery tables?
