How to add children to disconnected entity?

[Jim Talbut]

Hi,

I have a pair of entities: Assessment & AssessmentResults, with a 
One-to-Many relationship (an assessment can have many results).
The Assessment is modified whilst disconnected (outside of a transaction).
Is there any way to have AssessmentResults added whilst the Assessment 
is disconnected be persisted automatically when the Assessment gets merged?
Setting CascadeType.Merge doesn't seem to do it (I think that merges 
existing children, not adds new children).

Thanks

Jim
