I'm using an mx:List and displaying the data through an external item renderer. An array collection is where I am getting the data from, and hooking them up via data binding. There are about 200 items in the array collection. When I scroll down my list from about item 160 downwards, the icon associated with that line gets cut off and if I scroll up and down, the icon renders fine, sometimes gets cut off. I'm not using Blaze DS and can't at this point since my team won't for this release. It just seems like the item renderer is slow from about 160 downwards?
If you are loading icons from the network, you might be queuing up too many
requests. If the icons repeat, look into using SuperImage from
quietlyscheming.com to cache the icons.
I can't use SuperImage since the icons I'm loading do not repeat. Anyone else out there have this experience? And can share their solution(s)?
