Massimo Lusetti closed TAP5-300.
--------------------------------

    Resolution: Won't Fix

Scriptaculous has been update and work has been done on the JS side to make it more PrototypeJS agnostic (in future) so please reopen if still applicable in 5.3

>             Project: Tapestry 5
>          Issue Type: Bug

>    Affects Versions: 5.0.15

> If you place autocompleter on a page longer than browser's window (page which has a scrollbar) and press ArrowUp key after choice list is displayed whole page is scrolled down such that highlighted option is on the top edge of browser's window. If you press ArrowDown page is scrolled back to proper position. Behaves the same in FF and IE.
> Maybe this is the problem:
> markPrevious: function() {
>     if(this.index > 0) this.index--
>       else this.index = this.entryCount-1;
>     this.getEntry(this.index).scrollIntoView(true);
>   },
>   markNext: function() {
>     if(this.index < this.entryCount-1) this.index++
>       else this.index = 0;
>     this.getEntry(this.index).scrollIntoView(false);
>   },
> scrollIntoView true for previous and false for next?
> It's very annoying, and makes autocompleter practically unusable on production quality pages.
