NSComboBoxDataSource problems

Hello,

I am not sure how to categorize this problem so I will just explain the circumstance.

I am writing my first Cocoa application and I am trying to dynamically fill a ComboBox. In order to do this I implemented the required methods in my UiController implementation as follows:

  - (NSInteger)numberOfItemsInComboBox:(NSComboBox *)aComboBox
  {
      return 3;
  }

  - (id)comboBox:(NSComboBox *)aComboBox objectValueForItemAtIndex:(NSInteger)index
  {
      NSArray *text = [NSArray arrayWithObjects:  @"Jazz", @"Acid", @"Funk", nil];
      printf("Get index %d\n", index);
      return [text objectAtIndex:index];
  }

When I run the program the console displays the message:
  2008-08-26 08:59:46.417 CSAFEApp[14163:10b] *** Illegal NSComboBoxCell data source (<MyController:   0x134360>).  Must implement numberOfItemsInComboBoxCell: and comboBoxCell:objectValueForItemAtIndex:

In preparation of this email, I created a new Cocoa project which contained a window with a single combobox and a UiController. The above code works in the simple project!

Now I am completely confused. My suspicion is that there is lingering garbage in one of the project files. To work around this I tried to create a brand new controller class, made the datasource connections in the Interface Builder and got the same results. I also tried a build clean all with no luck.

What can I do to diagnose and fix this problem?

Thanks
Allen

PS: The version of Xcode and Interface Builder are 3.1
