Hi Martin,
I archive the selectionIndexes of the array controller and store them
within thecore data document's metadata. I think you need to serialize
(archive) the selectionIndexes to be able to save it either in
NSUserDefaults or anywhere else.
When loading a CD document I check if the meta data have the
appropriate entry, and if so, call the array controllers
setSelectionIndexes method with a delay of 0.0 (to get it executed in
the next run loop). Works like charm.

I have a core-data document-based application that uses a
NSTableView with an NSArrayController as its data source. I have
managed to figure out the magic IB incantations required to save the
column sort, order and hidden data to the shared NSDeafulsController.
What I would like to do is to also save the current selection of the
table across application invocations. I have tried the obvious:
- bind the array controller's selected indexes to the Shared
Defaults controller - no luck
- bind the tableview's selected indexes to the Shared Defaults
controller - no luck
I even tried to get the select programmatically, but when I tried
the callback methods I thought appropriate:
- windowControllerDidLoadNib
- applicationDidFinishLaunching
I found that the array controller was not yet loaded with data and
therefore had no selection.
