Once an EC has objects in it, its shared EC won’t get changed if a new default 
is set.  The notification is ignored.

Thanks a lot!

(Why on earth don't they mention this on the ERXEC documentation page? Oh, 
never mind.)


Did that fix it?

Well, sort of.

It gets curiouser and curiouser — in other words, I must be doing something far 
wrong.

When I set the “ERXEC.useSharedEditingContext” property to true, then

- the newly created ERXEC gets a shared editing context immediately upon 
creation, not later upon receiving 
DefaultSharedEditingContextWasInitializedNotification;
- and it is a different shared EC instance, not 
EOSharedEditingContext.defaultSharedEditingContext()
- but it is EOSharedEditingContext.defaultSharedEditingContext() who reads in 
automatically all the shared EOs
- and therefore, when fetching EOs through the ERXEC, I am still getting 
non-shared ones in the ERXEC (for its own sharedEC is empty, and thus 
EOSharedEditingContext.defaultSharedEditingContext is ignored).

Can you make any sense of that?

Thanks again a very big lot,
OC

   Hi there,

   the EOEditing context doc pretty unequivocally says

   ===
   By default, an editing context that has no shared editing context listens 
for DefaultSharedEditingContextWasInitializedNotifications. If a notification 
is posted while the context has no registered objects, the editing context sets 
its shared editing context to the newly initialized default shared editing 
context.
   ===

   Should it apply for an ERXEC, too? I sort of inferred it would, but by my 
testing, it does not seem so: an ERXEC I make (through 
ERXEC.newEditingContext()) seems to adamantly stay without 
sharedEditingContext, although the notification is posted all right (I have 
observed it myself to be sure), and if there's a good ole EOEditingContext, it 
indeed duly sets its sharedEC at the time.

   Have I missed something of importance somewhere? The ERXEC documentation 
does not say essentially anything of the sharedEC, far as I can say:

   http://wonder.sourceforge.net/javadoc/er/extensions/ERXEC.html

   In principle, I could work around the problem by setting the sharedEC to all 
my ERXECs programmatically -- that works all right --, but it would be a lot of 
work, with a danger I overlook something somewhere and got bit in the tender 
parts by that...

   Thanks,
   OC
