Not sure if that's the "official" way, but here's how I do it:

- (void) awakeFromNib
{
  [...]

  [myComboBox setEnabled: NO];
  [myComboBox setAction: @selector(_comboSwitchWord:)];

  [...]

  return;
}

- (void) _comboSwitchWord: (id) sender
{
  if( [myComboBox numberOfItems] > 1 )
    [myComboBox setEnabled: YES];
  
  [...]

  [myComboBox setNeedsDisplay: YES];
  [myComboBox display];

  return;
}

NSComboBox-setEnabled: only refers to the "drop down" button, not its
text field...
