OK... I got a little further:

group.children.Load(MergeOption.OverwriteChanges);

Does cause the children to refresh. Unfortunately... when it comes to the AssociationChanged Event:

"Events may be suppressed during bulk operations, such as Load, Attach, and Clear."

So I'm still searching for a way to update anything else that might need updating and I'm unsure how it will behave in WPF. (I'll have to test that.)
