Hi,
In my case, I can't insert objects in the editing context at their
creation but only at the end of the transaction because the user
can cancel his action at any time.
Doing as decribed works (I do it myself) but if I do so, I will
need to call at editingContext.revert()
to prevent unwanted changes to be saved in the database by another
part of my app using the same context.
To sum up, I'm just looking for a method like
EOEditingContext.awakeFromInsert except that it would be called
before inserting objects instead of after.
This way I could insert relationship members in the editingContext
for each EOCustomObject in their own classes and avoid huge code
blocks of insert
in my main controller
Frederic,
You need to rethink your apps structure as this *will* lead to
trouble and it breaks the EOF commandments.

Don't bother arguing that it works for you :-), we've been down this
path many times, check the list archives.
The correct solution is to create a peer or child EOEditingContext to
wrap a potentially disposable action so your users can walk away
without penalty and *always* insert your EOs right away.
