Vincent Sevel commented on EJB-314:
-----------------------------------

Emmanuel, I have just checked in a shorter test case (see above).

There I have a custodian persisted to be gin with (it contains no account).
I create an account, then add it to the detached custodian (with the back pointer set; ie: cust.addAccount), and finally persist it.
before I return from the method associateNewAccountWithExistingCustodian, I print the content of the account collection and here is the duplicate :

2007-09-17 09:28:16,578 [DEBUG] com.lodh.position.custodian.entity.CustodianTest - [CustodianAccountEty#1, CustodianAccountEty#1]

I was expecting only one (since I added only one) :

2007-09-17 09:28:16,578 [DEBUG] com.lodh.position.custodian.entity.CustodianTest - [CustodianAccountEty#1]

hope that clears things up.

> Doing a persist on a new object that has been added to an unitialized persistent bag, with lead to this collection containing 2 times the same new instance.
> However, if the collection is forced to be initialized before the persist, then it behaves correctly. 
> This was working in 3.2.1, not anymore in 3.3.1.
> Look at the method findOrCreateCustodianAccount in test_code_between_open_close.txt and the XXX comments.
