I have an interesting problem. I have two childBOs that will always have exactly one instance and expect them to be added along with the parent information in the form. Your examples show instances where one of more children exist, nice separate event allow the insertion of children. To be sure I have need of there as well, but first how would you recommend I proceed with the 1-to1 children?

What is the EditingState of the child business object after you call Add()?

Derrick,

This is a side note, but would it be possible for you to make it out here for the December training class?  I think it would dramatically speed your decision making and development process up.
