Have you tried setting keepReferencesOnCopy=1 on the field which
references the sub-event?
keepReferencesOnCopy seems to be a dead horse. There is no code -
neither in Archetypes
nor Plone actually using it :-)
Mmm. I have rfields=self.Schema().filterFields(type="reference",
keepReferencesOnCopy=1) in Referenceable.py. Some of my content types do
not work if I do not make use of keepRefs.
It was only introduced in Archetype 1.5.8 I think.
