Hi Chuck,

I thought that we _always_ need to lock the
EOObjectStoreCoordinator and EODatabaseContext even if we have already
locked the EOEditingContext because other EOEditingContext's could be
accessing the them at the same time on a different Thread. Isn't this
correct or is this a special exception to the rule?
You need to lock it if you are going to call methods on it. There are
probably some safe methods, but I'd rather lock. In your code above,
you do need to lock the context around the snapshotForGlobalID call.
I thought so.
Do you think i need to add locking the EODatabaseContext if i have
already locked the EOObjectStoreCoordinator? (I noticed in
EODatabaseContextAdditions that you don't)
On a side note, I noticed you (or Pierre; i'm not sure who wrote that
method) are doing the same thing as i am doing without locking either
EOObjectStoreCoordinator or EODatabaseContext in
com.webobjects.eoaccess.utilities.Utilities.faultForSupposedPrimaryKeyValue().
Thanks
