cannot access appDelegate NSMutableArray but I can access and modify an appDelegate int
===

I've got 2 types of var in my appDelegate : int and NSMutableArray
I can access the int var in my viewController but cannot access the NSMutableArray

Here is the code : 

appDelegate.h

    #import <UIKit/UIKit.h>  
    @interface AppDelegate : UIResponder <UIApplicationDelegate,NINetworkImageViewDelegate,FBSessionDelegate, FBDialogDelegate> 
    {
        UIWindow *window;
        UINavigationController *navController;
        int nbNewsNonLues;
        NSMutableArray *tableauNews;
        
    }
    @property (strong, nonatomic) NSMutableArray *tableauNews;
    @property (nonatomic) int nbNewsNonLues;
    @end

these var are well initialized in AppDelegate.m (checked it)

then I try to acces them with this code in ViewController.m

    @synthesize appDelegate = _appDelegate;
    
    - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil 
    {
        self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
        if (self) {
            // Custom initialization
            appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
            NSLog(@"%@", appDelegate.tableauNews);
            NSLog(@"%d", appDelegate.nbNewsNonLues);
            NSLog(@"%@", appDelegate);
        }
        return self;
    }
the log returns

2012-07-23 02:58:21.475 Aviso_0.1[2990:11303] (null)

2012-07-23 02:58:25.432 Aviso_0.1[2990:11303] 2

2012-07-23 02:58:25.432 Aviso_0.1[2990:11303] <AppDelegate: 0x7061340>

So I cant access tableauNews but I can access and modify nbNewsNonlues??


I know this is a noob problem but I read and googled for hours, there must be smthing I missed about delegation

Help needed,
