hi al,
can u explain the strategy us described reviously

Given the ID in the debtor class is an int.
| public void setId(int id) {
| this.id = id;
| }

I have a question
1) The default value with be '0'. How does the entitymanager.merge
differenciate between '0' default and a debtor.setId(0)?
I can see how it can identified as 'null' by using a Integer object instead of
an int.
many thanks
