So the exception happened after you deleted components in null layout in two steps, then undone.

I've been trying to reproduce this but no luck. Are you still able to repeat (reproduce) the steps that lead to the exception? Can you provide a test case or step by step description? Thanks.
Comment 3 ytn01 2012-06-19 12:14:29 UTC 
Yes that was what I was doing when the exception got generated.
Unfortuntely, I wasn't able to reproduce the exception again. :(
