Thanks for the fix, it works. Just curious about another consequence of 
the code refactoring: I wrote in this thread:

"The reason for the non-working of the code in contrary to the March 
code is that in updateAddresses() the items in the collection 
newAddresses and oldAddresses are different, the equals() or here 
contains() does no longer work."

Due to this change in

private Collection updateAddresses(Collection newAddresses) {
// massively shortened
     Collection oldAddresses = _conn.getCollectionByQuery(q);
     Iterator oldAddressesIterator = oldAddresses.iterator();

     while (oldAddressesIterator.hasNext()) {
         Address oldAddress = (Address)oldAddressesIterator.next();
         if (!newAddresses.contains(oldAddress)) {

the test !newAddresses.contains(oldAddress) always returns false. OJB 
handles it internally so that no db access will be done if not 
necessary, i.e. if the "same" elements (in OJB sense, but different in 
Java sense) will be readded in the same tx.

But the behaviour is a bit strange. Is this by 

Thanks again for the fix in time for the customer presentation tomorrow ;-)
