thanks a ton David !! I was almost about to give up on Laslo prototype

entire night to pull of prototype ....btw I tested this code with
legals it works fine :-) .....
You are very welcome. Glad to hear it worked on Legals too. OL has
proved over time to be very capable and flexible enough to work around
most perceived shortcomings.
I have also added this in OpenLaxlo wiki for others to benefit ->
http://wiki.openlaszlo.org/Tips_and_Tricks
i noticed this single line did the magic -> scroll.page(1) ->
i tried to search in documentation but could any relevant section
...could also tell us briefly what it does ?
The LZX Reference manual defines the page() method on the bascrollbar
tag. Note scrollbar extends basescrollbar.
Paging is essentially a way to reposition the slide position of the
scrollbar. You can reposition the scrollbar N pages up or down on a
single call, the number of pages is determined by the parameter passed
on the call. The size of a page is determined by the height of the
scroll target, that is the view being scrolled.
In this case scroll.page(1) will attempt to slide the scrollbar down one
page each time a chat user submits some text. Given typical usage
suggests only a few lines of text will be added at a time this provides
the effect you require.

Thnx,

Best of luck with your presentation.
