It seems you are content to stick with the workaround, but I'm curious if you are getting the data from index 4, even though it's saying index 5, or if you are getting the data associated with index 5. I've seen this where the selectedIndex was 5, but the data was from the old index 5 (now 4 or 6), which really does mess things up. I've had to go and programatically clear the DG and re-assign the dataProvider to keep things consistent, but that's not problem free when inserting into the DG. Frustrating :-)
