@Didier - I have considered this, and I guess I will have to manually
delete each entity if I cant find a more elegant solution, however
going by what the documentation says it should just work. I'd like to
find out why this exception is occurring if possible.
@Nichole -
To add to my last comment I could do:
pm.deletePersistentAll(children)
to delete all Child objects in the Parents children Set, however as
the method deletePersistentAll has a void return type how do you
ensure all Child objects have been deleted before I delete the Parent
entity?
