Edit NSTableView - NSArrayController

Hi at all I have some problem tryng to editing value inside nstableview, I binding the table with an nsarraycontroller, for add and editing a value I use this methods:

- (IBAction) addNewMateria:(id)sender{
        isNew = YES;
        Materia *newMat = [[Materia alloc] init];
        [self.arrayMaterieController addObject:newMat];
- (void) editingDidEnd:(NSNotification *)notification {
             NSTableView *table = [notification object];
             Materia *newMat = [[Materia alloc] init];
             if([table selectedRow] != -1) {
                 NSArray *selectedObjects = [self.arrayMaterieController selectedObjects];
                 newMat = [selectedObjects objectAtIndex:0];
             if (isNew == YES) {
                 if (newMat.idMateria != nil && newMat.titoloMateria!= nil && newMat.iconaMateria!= nil){
                     NSString *strQuery = [NSString stringWithFormat:@"INSERT INTO Materie (IDMateria, TitoloMateria, IconaMateria) VALUES ('%@', '%@', '%@')",
                     [dataLoad  update:strQuery];
                     isNew = NO;
             else {
                 NSString *strQuery = [NSString stringWithFormat:@"UPDATE Materie SET IDMateria='%@', TitoloMateria='%@' ,IconaMateria='%@' WHERE IDMateria='%@'",
                 [dataLoad  update:strQuery];

- (void) controlTextDidBeginEditing:(NSNotification *)aNotification {
        if ([[aNotification object] isKindOfClass:[NSTableView class]]) {
            NSLog(@"Tabella strt editing");
            NSTableView *aTableView = [aNotification object];
            if (aTableView == tabellaMateria) {
                self.materiaOld = [self.arrayMaterie objectAtIndex:[aTableView selectedRow]];
my problem is that when I edit a value the object oldMaterie change with new object, so I can't update the value on my database because I can't store the old id of object, where is the mistake?
