Heya,
If you have an isNew() method on your EOs to check if they are new in
their editing context you could try filtering using that too.
Something like this (or the WOnder equivalent):
new EOKeyValueQualifier(
"isNew",
EOQualifier.QualifierOperatorNotEqual,
Boolean.TRUE
);
Might be handy if you really need to add the relationship first, or if
you want to avoid using multiple ECs.
Cheers,
David

Hi all,
Is there a way for me to add an object to a to many relationship (list
of objects) without leaving the page or representing the newObject both
in the list and in the edit interface?
For example:
Meeting edit page
Attendees:
John
Mary
Edward
add new attendee(button)
When you hit the "add new attendee" button you get the new person object
displayed in both the list and associated with the edit interface.
John
Mary
Edward
(new person)
name: (new person)
(save) (cancel)
The attendee has a mandatory meeting relationship, so it is added to the
meeting upon creation. The new object is displayed as the final object
in the to many relationship even before saveChanges is called on the
editingContext. Is it possible to show only the objects in the
relationship that have already been saved to the database and the newly
created (but not yet saved) object separately?
Normally I would add the attendee on a separate page and on save come
back to the original meeting page but I would like to eliminate some
jumping around if possible.
Thanks,
David
