I am getting strange behavior also, I just didn't realize it earlier. I keep getting the following error when I try to insert rows in a newly created section I add between two other sections (there are a total of 3 including this one, it is going in the middle of the two). If I just add the section (and not the rows)it works fine, but the cells that were already on the screen don't update. When I add the line to insert the rows I get the error. The thing is it starts with one section and you can add the last two in either order, but they always have the same index when added. If I use this same code when I only have one section and add it to the end it works. I can even add the third section after it after that without problems. It seems to be happening after committing all the row changes in my code while the tableView is doing it's thing. Seems like there could be an issue with TableViews, but I never added rows like this before beta 6 so I could be doing something wrong. I have looked over my code for the last 3 hours piecing it apart though, and I am starting to think it could be that tableView has some issues.
