Before going on in a more deep question, and because I was unable to find some infos with a canonical search, I would like to ask you this:

1) I have class A in a composite element in a list
2) if cascade="all-delete-orphans" in the mapping is defined, I have a "Persister not found" exception for class A.
3) if cascade="all" all works fine.
4) I don't really have any orphans !!!!!!

Is all that correct ? Do you think I miss some understanding of the inside working of all-delete-orphans ?
