Well, I got it fixed but to be honest I'm not entirely sure why, or what, was causing the problem. I removed all the auto-requery stuff from my parent and my child bizobj and the problem went away. I had made a few other changes at the same time, but I think it was the requerying that did it. I had been hoping to post a nice followup message with an explaination of what had been happening, but it doesn't look like that's going to happen.
