CSS Overflow property, scrolling in Scriptaculous Autocompleter

Does anyone else have trouble with the scroll bars when using the
Scriptaculous Autocompleter?

I have set the CSS overflow property for the autocompleter class to
scroll (I have also tried auto with the same effect), and while the
scroll bars render just fine, the following happens: I try scrolling,
either by clicking in the scroll bar or dragging the thumb, and the
browser seems to interpret that as clicking behind the scroll bar, on
the canvas. The autocomplete list disappears without ever showing
the next set of selections. In fact, when I drag the thumb, the
browser crashes completely.

(If I click on the content of the list somewhere in the first set of
selections, it works as expected and fills the list selection into
the text box.)

I am using Safari and recently upgraded to version 3.0.4. The
crashing seems to be a new... um... feature (it's possible I didn't
test the dragging of the thumb before), but the failure of the list
to scroll was present in Safari 2.

Any suggestions?

Thanks,
-- Sigrid.

Maybe you have more success getting an answer to this non-Seaside
related question when asking in a script.aculo.us forum or irc
channel?

Hi Lukas,

Thank you. I may try that. However, I am using Scriptaculous in
Seaside, so I thought I might not be the only one on this list with
this problem.

Hi again,

There have definitely been others with this problem. A search of "overflow autocompleter" on this link reveals several posts discussing the issue. Unfortunately, I am a seasoned Smalltalker who does not speak Prototype or Javascript, and I haven't the foggiest idea what they're talking about in their proposed solutions.

How do I incorporate suggestions like this (from the web site http://elia.wordpress.com/2007/01/18/overflow-smooth-scroll-with-scriptaculous/):

From time to time while developing with script.aculo.us I needed smooth scrolling for an “overflow:auto” element:
finally I got it: http://dev.rubyonrails.org/ticket/5118
If you want to scroll to a specific element inside the container, follow this example:
function moveTo(container, element){
Position.prepare();
container_y = Position.cumulativeOffset($(container))[1]
element_y = Position.cumulativeOffset($(element))[1]
new Effect.Scroll(container, {x:0, y:(element_y-container_y)});
return false;
}
where Position.cumulativeOffset($('target-id')) gives you an array with the absolute position of that element.

into Smalltalk/Seaside?

Here's another suggestion from the rubyonrails-spinoffs list that I can't make sense of. Again, how do I make this work in Seaside?

From Sept 5:

My project recently came across a problem where the autocompleter
selection list dissapears if you try to use scrolling on it in IE.
This seems to be a known issue, with patches submitted.
refer (http://dev.rubyonrails.org/ticket/6560, http://dev.rubyonrails.org/ticket/4782,
http://dev.rubyonrails.org/ticket/8163 )
So we have fixed the problem on our project by forking scriptaculous
and applying one of the patches.
Since there seems to have been some history with this problem, I'm
just wondering what the current state of play is?
Is it likely that a patch for this will make it into an upcoming
release?
cheers
Perryn

follow-up post from Nov 13:

2 month later, a new release of scriptaculous is out but the bug is
still here :(
Which patch (among the many proposed) did you choose to fix your problem?
Thanks,
Nicolas Terray

Any ideas or guidance would be greatly appreciated.

-- Sigrid.
