Thanks Kieran. Good advice. Off the top it appears I might still have
trouble with my batch navigation bar (any thoughts on that?) but I'll
give it a go.

Clarification, I would of course make a local instance in the same ec
as the display group before doing that! :-) IIRC,
ERXBatchingDisplayGroup may have some behaviours that are different to
regular ERXDisplayGroup .... but cannot remmeber off the top of my head.

Hi Jon,
I typically use a peer ec, and once user submits the new item, I
would do sth like this (which I just copied/pasted from working code.
BTW, the display group is ERXDisplayGroup and is using a
DetailDataSource in this case:
recipientsDisplayGroup().insertObjectAtIndex(newRecipient,
0);
recipientsDisplayGroup().setSelectedObject(newRecipient);
recipientsDisplayGroup().displayBatchContainingSelectedObject();
Note I insert new ones in furst position of first page just so user
gets visual feedback. You can insert wherever.

for help.
* Page has a display group (ERXBatchingDisplayGroup) using EC1 in
the fetch spec. For the sake of example the EOs in the list are
colors - 25 total with 10 on each page. Colors are sorted by name.
* The second page contains GREEN through PINK. User clicks on ADD
COLOR.
* Lightbox (AjaxModalDialog) appears and allows user to edit the new
color in a peer or nested editing context - EC2. My usual approach
is to use a nested ec.
* User adds ORANGE and saves changes. Lightbox disappears.
Container surrounding the display group is updated.
What is the best way to update the display group at this time? I've
tried calling fetch(), redisplay(), updateDisplayedObjects(),
combinations of the above, etc. with various levels of success but I
always run into trouble with something. Either the list doesn't
refresh correctly re: sort order or the batch navigation bar doesn't
know when the batch count increases. The only sure fire way I've
found is nullifying the display group and starting over. This seems
very inefficient and I'm sure I'm missing something.
I don't want to use the same editing context to edit as I need to
discard the insert on cancel/overlay dismissal of the AMD. I
realize it is possible to use a single ec and revert but it grates
me to jump through those hoops when a second ec is so easy. The
only problem I have with the latter is getting my display group and
associated batch navigation bar updated consistently and correctly.
Thanks in advance,
Jon
