Folks;
Using 10.5 SDK deploying to 10.4 on an Intel 10.5.7 machine running XC
3.1.2
I have a Core Data model against which I have successfully loaded data.
Now I want to display some data in a tableView - so I drag a stock
arrayController from IB onto a window.
I set the Mode to 'Entity' and state the Entity name and check
'Prepares Content' (not 'Laxy' - not supported on 10.4)
No FetchPredicate - I'm just trying to build up incrementally...
I bind the controller's ManagedObjectContext to the windowController's
exposed manageObjectContext
Hook up a tableView with one column to display some data from the
controller,
Compile - no errors
Crashes immediately after the windowControllers -awakeFromNib with
this stack:
#0 0x92aa1e17 in objc_exception_throw
#1 0x92fd6e8b in +[NSException raise:format:arguments:]
#2 0x92fd6eca in +[NSException raise:format:]
#3 0x937b4019 in -[_NSManagedProxy _managedObjectContext]
#4 0x937b404a in -[_NSManagedProxy _persistentStoreCoordinator]
#5 0x937b40d8 in -[_NSManagedProxy _entity]
#6 0x937b421e in -[_NSManagedProxy usableSortDescriptorsFromArray:]
#7 0x936568d2 in -[NSArrayController(NSManagedController)
defaultFetchRequest]
#8 0x937b3a98 in -[NSObjectController(NSManagedController)
_executeFetch:didCommitSuccessfully:actionSender:]
#9 0x938e3032 in _NSSendCommitEditingSelector
#10 0x936c9d78 in -[NSController
_controllerEditor:didCommit:contextInfo:]
Core Data is up and running by the end of the windowController's -
awakeFromNib.
If I remove the controller - everything is fine.
If I simply uncheck 'Prepares Content' the application will launch but
there is no data shown in the tableView.
What am I not seeing here?
Steve
