Kevin,

>If you open up mmBusinessObject.cs and do a search for "ParentKeyValue" you can see it is set in the StateChangeHandler method. The StateChangeHandler method fires for a child business object whenever the state of the parent changes. In the "default:" case of the switch/case statement the ParentKeyValue property is set from the event arguments passed from the parent to the child business object.

>Have you registered the child object with the parent?

Yes, the child is registered with the parent. At the end of mmBusinessObject's StateChangeHandler method switch/case statement default case the event argument e.PrimaryKeyValue is always undefined. :(

And, yes, the PrimaryKey field is properly populated.

I'm seeing rows undefined in the Saving and Saved states, yet changes are being written to SQL Server except for the foreign key.
