And if you're using wonder... ERXGenericRecord's isNewObject()... :)

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
