I have a class which has a collection of itself as its children. It is
mapped as :
@Persistent
private Group parent;
@Persistent(mappedBy= "parent")
private List<Group> children;
The problem is I cannot insert the root object. The call to
makePersistent comes back successfully, but the entity is not in the
database. I guess this object with this mapping can not have null
parents. Is there anyway I can make the parent nullable?
