hmm, the "just keep it" part is what I'm not sure how to do for
something that is only held via a weak reference from the tree being
cloned ;)
deepClone() would need to be able to return something like
std::vector<FieldContainerUnrecPtr> for all parent-less weakly
referenced containers in the cloned tree to make sure that there is at
least one strong reference to keep them alive.
Cheers,
Carsten
