I don't know if you can do that in the model (the @sum) or not.
Also, flattened attributes can have inconsistency problems. I'd
lean towards the Java solution.
You mean, skip flattened attributes in total? Yeah, that would
probably be easier to figure out. I was thinking of flattening stuff
because I assume that would increase performance... I suppose I'll
just try a Java only solution and see how it behaves...

btw, I guess by "inconsistency problems" you mean that flattened
attribute values get cached and are not updated when something in the
chain changes? I ask because if that's what you mean I can still use
keypaths to easily obtain values in my Java methods...
