You have a partial response at the end of the link: The JDO
implementation does the work to delete dependent child objects, not
the datastore. If you delete a parent entity using the low-level API
or the Admin Console, the related child objects will not be deleted.
So, I you play with entities outside of JDO (i.e directly through low-
level API), no cascaded delete.

Hi didier,
I wanted to say that I don't want to make an owned relationship, i.e. I am
not using any field to list TestChild entites in Test class as given in the
example :
@Persistent
@Element(dependent = true)
private List childs;
The only thing I am doing is to set parent key in each TestChild entity so
that both Test and TestEntity come into same entity group. The problem here
is that cascade delete doesn't work now.

Hi Prashant,
dependent entities are deleted when parent is: see

Hi,
Suppose, I have two types of Entities Test and TestChild. For all
TestChild entities i have set key as child of some Test entity (because i
want both entities in same entity group to support transaction) but i
haven't mapped TestChild entity to any variable in Test entity.
Now, i am wondering if there is any way, such that, if i delete Test
entity
then all corresponding child TestChild entitie(s) should also get deleted
?
