Greetings:
I'm working with Apple's Core Recipe example: "Example 4 - Working
With Core Data and Cocoa Bindings""
1) I've successfully built and ran a simple Chef-Recipe-Ingredient
example using Core Data + Binding code.
2) I removed the original IB objects from the window and Alt-Drag the
Chef Table (Entity) into the Window object. Again, runs okay.
2a) I now have an Instantiated "Chef" NSArrayController and a
CoreRecipesController (son of NSObject) in my IB.
Okay, all is well.
I want to add a simple double-click functionality to the NSTableView
that contains the list of Chefs. Reading the assorted docs, it
appears strait forward.
3) I select the Binding properties of the NSTableView via the Inspector.
This is what I have:
DoubleClickArgument:
Bind To: Chef Array Controller (NSArrayController)
Controller Key: selectedObjects
Selector Name: "inspect"
DoubleClickTarget:
Bind To: CoreRecipesController(CoreRecipesController)
Controller Key: nil
Model Key Path: self
Selector Name: "inspect"
============================================================
The target:
...
...
@interface CoreRecipesController : NSObject
{
NSManagedObjectContext *managedObjectContext;
NSManagedObjectModel *managedObjectModel;
NSMutableArray *recipeArray;
IBOutlet NSWindow *mainWindow;
}
- (NSManagedObjectModel *)managedObjectModel;
- (NSManagedObjectContext *)managedObjectContext;
- (NSMutableArray *)recipeArray;
- (IBAction)saveAction:(id)sender;
- (void)inspect:(NSArray *)selectedObjects;
@end
@implementation CoreRecipesController
...
- (void)inspect:(NSArray *)selectedObjects { // via column
Binding ACTION
NSLog(@"{inspect}");
} // end inspect().
...
@end
========================================================================
============
4) I rebuild and ran the altered example:
a) I got the Chef data displayed.
b) Double-Clicked on the NSTableView of Chefs: ****bomb****
Error:
CoreRecipesCocoaBindings has exited due to signal 10 (SIGBUS).
I followed the documentation an worked on a working example. All I
did was to add the additional double-click functionality.
Any clues to what I'm missing?
