How have you set up the bindings?
As I wrote in the previous emails:
The textfield in Details.nib,
- Bind to: "Items"
- ControllerKey: "selection"
- ModelKeyPath: "title"
The Items array controller in Details.nib (managedObjectContext
parameter),
- Bind to: "File's Owner (MainController)"
- ModelKeyPath: "managedObjectContext"
and MainController implements:
- (NSManagedObjectContext *)managedObjectContext
{
return [[NSApp delegate] managedObjectContext];
}
You haven't said how you've set up the bindings for the table view.
At a *guess* you have set a 'content' and/or 'sortDescriptors'
binding for the table view itself, but not 'selectionIndexes'. If
this is the case, then you need the latter as well (typically bound
to [Items].selectionIndexes).
btw, if only you could come here in switzerland and give to our
university the same great course you're giving at Stanford.... (I'm
afraid students here we'll never see a Cocoa course...that's too bad)
;-)
I did give an OPENSTEP course in Lucerne a few years ago...
