[jboss-user] [EJB 3.0] - Re: deleting entities from a Collection

[aberezin]

Thanks for the tip.

I could seem to get CascadeType.DELETE_ORPHAN to work in 4.04ga with a Set (didnt try with a List).  I saw a bug related to this, http://opensource.atlassian.com/projects/hibernate/browse/EJB-53 but it appears fixed long ago.

I made a little test case that persists the Order with one OrderItem.  I then call order.getOrderItems().clear() and then call (thru the sessionbean) em.merge(order) and even do an explicit flush().  The underlying row for the OrderItem is not deleted.

This whole thing is not a big deal since I can explicitly delete the child objects no longer in the Set.  I was just curious as to how to do it automatically.
