Re: [flexcoders] List Scrolling Width Issues
Yesterday I was using a itemRenderer based on mx:Image and must to change to
runtime BitmapImage like this one:

so I recomend you to go that way

If you search the archives, you’ll see that image-based renderers cause
lots of problems.

it can only scroll 1 or 2 more images but in fact there are about 20 images.
As you start scrolling the list figures out that there are more and adjusts
the scroll bars. It keeps doing this until we reach the last images and
finally the scroll bars work as expected.
What I don't understand is the data group next to it works exactly how I
