Hi, Good timing as I think I'm trying to do a similar thing: highlighting rows in a List via an item renderer and "highlighted" property on the data model. After updating the data model, I plan to call refresh() and expect it will automatically fire the item renderer for each visible row; the renderer will detect highlighted rows via the data property and apply an appropriate style. Will my approach work or are you saying I'll need to explicitly dispatch events?
I'm not using a custom gradient and so am not too concerned about the bugginess you report but would love to see your general approach. Care to share some code? We can do it offline, if you wish: [email protected]. Finally, I don't get the part about indexToItemRenderer. Can't you do everything through the data model and data binding (using refresh) without iterating over the List itself?
