How many items? This might be easier with Repeater.

The one on the left displays the names of some "bundles" - e.g. "Bundle 1" The one on the right displays the items in the selected bundle, plus a percentage value - e.g. "item1 - 10%" "item2 - 55%" "item3 - 61%" The items are the same for all bundles, but their percentages may change as the user selects different bundles. If that happens I want to highlight that itemRenderer. (eg when the percentage changes, highlight renderer) I looked at a similar example from Alex Harui - he compares a DataGrid's listData.UID to the previous UID (stored as a property on the renderer). If they match, he knows he has the same item and changes that value. I have implemented IDropInListItemRenderer (so I have access to the UID) but the renderer-recycling of the List means that even when the UID's match, the "oldPercent" value I stored doesn't actually match up to item being displayed - in other words, the renderer which previously displayed "item1 - 10%" may now be displaying "item3 - 61%" , so the percentage HAS changed, but that's because it's displaying a different item! Is my only option to send both the new% and old% in via the dataprovider, or is there another way to get around this issue? Cheers
