I spoke too soon, should have said "I can _try_ to provide". Took a while  
to reproduce it in fact. The changeset is attached. You'll need to create  
a GOODS database at port 6103 and run the following to populate data.

============
db := KKDatabase onHost: 'localhost' port: 6103.

ac := HBAccount new.
ac addTransaction: (HBTransaction new amount: (HBMoney amount: 1)).
ac addTransaction: (HBTransaction new amount: (HBMoney amount: 2)).
db root at: #xx put: ac.

db commit
============

If you were wondering why the database is needed.., its because the DNU  
page shows alright without it. Also, if you show HBForceDNUInWATableSum as  
the root component, the DNU page also displays correctly. In addition, if  
you only store a list of HBMoney instances instead of transactions and  
modify the table display code accordingly (use #yourself instead of  
#amount), the DNU page shows also, funny.. Do let me know if I can help  
with anything or if I left out anything, thanks alot.
