Restoring sort order to NSTableView

I have an NSArrayController hooked to an array (of NSDictionary) and bound
to columns in a NSTableView. It all works fine. I added an auto save name to
the table so that the column widths and ordering are restored upon launch,
but can't get it to restore the sort order.

I can force a sort with:

NSMutableArray      *descriptors = [NSMutableArray arrayWithCapacity:0];
NSSortDescriptor    *descriptor;

descriptor=[[NSSortDescriptor alloc] initWithKey: @"name" ascending: YES
selector: @selector(compare:)];

[[myTableView tableColumnWithIdentifier:@"name"]
setSortDescriptorPrototype:descriptor];

[descriptors addObject:descriptor];
[descriptor release];

[myTableView setSortDescriptors:descriptors];

Of course this sorts by a fixed column. I was thinking I could call
sortDescriptors before quitting and save restore this using an NSData, but
really this should be automated.

How do do it?

Thanks,
