Hi Stephane,
My ask first what you exactly are trying to do? What is the reason you
would like to define the parent/child object within Hivemind and then
persist them?
Are the parent/child objects not simple beans just now which (without
involving hivemind) can be stored/retrieved etc using the DAO service
(which is defined in Hivemind as a service)?
Cheers,
Johan
