This is the primary controller for this entity type and fetch: isn't
pulling any data down, at least not in time for the next call to
arrangedObjects to verify that there's data, and certainly not in
time for setting the selection. I'd done something similar in the
past, so I expected that to work, but at this stage of document
initialization it's not doing anything.

Forcing the array controller to fetch should work. Is your array
controller bound to another controller? You'd probably need to tell
that one to fetch first.

I'm trying to have my document-based Core Data program remember
the last selection in the NSTableView and restore it at startup
with setSelectedObjects. I save the object ID URLs in a document
preference and restore them perfectly fine in
windowControllerDidLoadNib, so I know that Core Data has its store
and so on because I can use managedObjectIDForURIRepresentation to
locate the objects just fine at that point.
However, the NSArrayController that's powering the NSTableView has
no content at this stage, and I don't appear to be able to force
the issue by using prepareContent/fetch/rearrangeObjects or their
ilk. It'll load when it wants to. However, that breaks things
for me because calls to setSelectedObjects have no effect if
there's no content to select.
So ... has anyone run into this one and won? I'd prefer not to
use a hack, but if I have to, I have to.
