Hi all,

I have a table CN with primary key CN_NO. CN has one to many relationships with table CN_CLOS (which primary key is combination of CN_NO and CLOS_NO).

Program flow is like this:

Create CN_CLOS
Set CN.SETCNCLOS(CNCLOS); -- set CN_CLOS to CN without persisting CN_CLOS first
Persist CN (cascade type is Persist and Remove)
Flush

In many incidents i could see in the logs DuplicateKeyException on persisiting and the table involved is CN_CLOS. Please advice. Thank you very much.
