[b]Hibernate version:3.0.5 [/b]
I get the following exception, when I access by an extention of a DefaultPostLoadEventListener to a collection loaded from a DB2 Database.

I have set all lazy-flags to false. But there are more than 1 collection in the persitent-class, so the lazy-flags probably don't work for all colletions.

If I don't use the DefaultPostLoadEventListener and perform the action of this Listener after load the Object from the Database (session.get(..)), it works fine. Therefore I think, I access the collection before it is loaded.

Has anybody an idea ?? What can I do to access later to the collection ??

Since I changed fetch="join" to fetch="select" it works very good.

I don't understand why, but it works. So if someone has an idea I am still interested.

You are not allowed to invoke the collection from the postload callback.

I'm having a similar problem. What do you mean by postload callback? Will eager loading of the collection solve the problem?

Hi there,
so PostLoad method convertPhotos in example http://java.boot.by/scbcd5-guide/ch06s04.html will not work in Hibernate because it is invoked in the PostLoad callback method?
