Mike,
>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. :(
In that case you need to look at the parent business object to see why the primary key value is undefined. You can set a breakpoint in mmBusinessObject.CallStateChange() to determine this.
