Now I think this happens when you make a change to certain workflows and an
entirely new lsid is gotten, and the old one is placed in the derived from
list, instead of just bumping the revision. I'm not sure of all the cases in
which this occurs (it seems like this sometimes happens when it shouldn't, but
that would be a separate issue), but one is when you rename the workflow. When
a new lsid is assigned to the workflow, the call to get the workflow out of
ObjectManager in getProveanceRecorder returns null, even though the new lsid is
used:

NamedObj reference =
ObjectManager.getInstance().getHighestObjectRevision(lsid);
