Data getting lost between 2 ViewDidLoad calls

Inside a UIViewController class, I have a tableView who gets called like this by clicking on a navBar button:

-(IBAction) addButtonPressed:(id)sender {
    CreateQuestionController *createQuestionViewController = [[CreateQuestionController alloc] initWithNibName:@"CreateQuestionController" bundle:nil];
    [self.navigationController pushViewController:createQuestionViewController animated:YES];
    [createQuestionViewController release];
}

This method gets called nowhere else in my code. Well, when I click this navBar button and the view shows up I find out that the ViewD开发者_StackOverflow社区idLoad method gets called twice (which is normal in this case) BUT the data I enter here gets lost. Here's my code:

- (void)viewDidLoad
{
    [super viewDidLoad];    
    textView.text=@"Type your question here";
    NSLog(@"Question text:%@", textView.text);
}

Log:

2011-07-11 10:56:35.727 HelpMe[1343:207] Question text:Type your question here
2011-07-11 10:56:35.728 HelpMe[1343:207] Question text:(null)

What's going on? Thank you

Edit: Other symptoms: - Cannot push another view - Cannot change the image of a button

My problem was in my nib file. I deleted my controller and assigned all my outlets to the File's owner
