Dan Haywood commented on ISIS-234:
----------------------------------

It seems that we only ever call remapAsPersistent for root adapters, never for aggregated entities.  I
suspect this means that the OIDs of these aggregated entities cannot be trusted after the persist.

However, if the user does not do a flush (ie all persistence happens after the action is completed), then
this ought not be a problem, assuming that the objectstore is clever enough to know how to persist an
aggregated object.  I'm guessing that they could be, because - at least in theory - they have the context of
the root adapter being persisted.

~~~
If all the above is bogus, then the remapAsPersistent will probably need to be enhanced to also walk the
graph looking for aggregated entities that have a parent OID of the root adapter initially being
persisted.  (It either walks the graph, or just does a brute-force search through the ObjectManager's maps).

--------------------------------------

The other object stores also need to be able to store aggregate objects or fail gracefully. At the moment
only the NOSQL one is working.

----------------------------------

I believe the in-memory (dflt) objectstore is also working now; Rob was gonna look at the XML object store also.
