xib, designer and cs file

I'm updating an older project now with MonoTouch 5.0.3 and MonoDevelop 2.8.4.2. 
Everything works - except UIBarButtonItems. 
In XCode, the .h file looks like: 

@interface vcTimerChoose : UIViewController { 
        
        UITableView *_myTableView; 
        
} 

@property (retain, nonatomic) IBOutlet UIBarButtonItem *BarButton; 

@property (nonatomic, retain) IBOutlet UITableView *myTableView; 

- (IBAction)BarButton_Click:(id)sender; 
@end 

(pretty much the same as in the older VC in my project), but it doesn't work. 
When I try to compile the project 
partial void BarButton_Click (MonoTouch.UIKit.UIBarButtonItem sender) 
gives a "A partial method 'ShoCoIP.vcTimerChoose.BarButton_Click((MonoTouch.UIKit.UIBarButtonItem)' implementation is missing a partial declaration" error and 
BarButton.Title=NSBundle.MainBundle.LocalizedString("Settings","Timer Settings"); 
throws a "System.NullReferenceException: Object reference not set to an instance of an object" exception, though the exct same code works in other viewController in the same project (created with an older version of MonoTouch).

-> monotouch

If your application was made before Xcode 4.x then it likely needs to be updated to use [Outlet]s attributes. In this case the following document should help you:
