Facebook SDK 3.0-Error 5 When posting status update

I am trying out adding facebook integration in an app using the new (beta) facebook ios sdk 3.0. All I would like to is post a status update to facebook. I used a FBLoginView to login to facebook. I put my app id in the plist as instructed on facebook. I put in some code to post to facebook.

Code:

(void)viewDidLoad
{
[super viewDidLoad];
NSArray *perms;
perms = [NSArray arrayWithObjects:@"status_update", nil];
FBLoginView *loginview =
[[FBLoginView alloc] initWithPermissions:perms];
 
loginview.frame = CGRectOffset(loginview.frame, 5, 5);
loginview.delegate = self;
 
[self.view addSubview:loginview];
// Do any additional setup after loading the view, typically from a nib.
 
}
 
- (IBAction)poststatus:(UIButton *)sender {
NSString *message = [NSString stringWithFormat:@"Test staus update"];
 
[FBRequestConnection startForPostStatusUpdate:message
                            completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
 
                                [self showAlert:message result:result error:error];
 
                            }];
}
- (void)showAlert:(NSString *)message
      result:(id)result
        error:(NSError *)error {
 
NSString *alertMsg;
NSString *alertTitle;
if (error) {
    alertMsg = error.localizedDescription;
    alertTitle = @"Error";
} else {
    NSDictionary *resultDict = (NSDictionary *)result;
    alertMsg = [NSString stringWithFormat:@"Successfully posted '%@'.\nPost ID: %@",
                message, [resultDict valueForKey:@"id"]];
    alertTitle = @"Success";
}
 
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:alertTitle
                                                    message:alertMsg
                                                  delegate:nil
                                          cancelButtonTitle:@"OK"
                                          otherButtonTitles:nil];
[alertView show];
}

The odd thing is, this code works ONCE. After authenticating the user for the first time, I can post ONE status update successfully. After that, all subsequent attempts will fail with a FBiOSSDK error 5 (in the console, Error: HTTP status code:400). The only way to fix this is to remove the app from the facebook account and re-authenticate. I'm not sure what the problem is. I looked online for solutions but couldn't find anything. If anyone knows how to fix this, please let me know. Thanks

hmm I downloaded Facebook integration, then just logged in via "mail, contacts, calendars", restarted, and i have been able to update my status via the notification center without a problem... but maybe I'm not understanding what your trying to do.

No, I'm not talking about an error I get when logging onto Facebook in ios6, I'm making an app that integrates with Facebook and I am having trouble making it work..
