Did you get any binding warnings in the console? I'm not clear it knows how to wire up to that. You might just need to run the equivalent in a updateComplete event.

When the list data changes, I think the displaylist is invalidated, redrawn, and then this binding action happens and verticalScrollPolicy is set to 'on' ... but then the display list isn't invalidated again, so you don't see the width appropriately change until the next time the list data changes. Kind of odd. Alex - I'd assume that in the setter for verticalScrollPolicy the display list needs to be invalidated again. This may be a bug, not sure.

I think I'll set verticalScrollPolicy to {dataProvider.length()>rowCount?"on":"auto"}, so I don't have those blank scrollbars present when they're not needed ;p (haven't tested this yet, but hopefully it works) Btw, in googling to find out what lockedRowCount and rowCount were, I found your page ;) http://blogs.adobe.com/aharui/2007/07/the_future_of_list_classes_tre.htm l Thanks for taking time to answer my simple question, Seth From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Alex Harui Sent: Thursday, November 01, 2007 1:56 PM To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] problem with list component If verticalScrollPolicy="auto" (default), the scrollbars are not factored into the width so its appearance does not shift your UI.

However, if you then add items to this list causing it to require a scrollbar, the scrollbar does not increase the total width as expected, but instead is placed over (and thus hiding) the content the list previously was sized to. =( Anyone ran into this and found a workaround?
