Custom View Missing when using NSToolBar

Question

Hi all
I have a window with a custom view on it ( PreferencePanelWindowController.h .m .xib ). And I have two views ( PreferenceGeneral.h .m .xib and PreferenceLogging.h .m .xib ) which can be loaded into the custom view.
Now the General view loads when the window is opened however if I add an NSToolBar to the window then the General view won't load when opening the window.
This is the case both when I create the NSToolBar programmatically or if I simply use interface builder to pop the Toolbar on.
Why would this be and how would I get round this.
Incidentially I have tried reloading the view in awakefronib and windowdidload.
Cheers
Steve

Adding on from the above
I have
- (void)awakeFromNib
    [self buildToolBar];
    [self changePreferencesViewController : kPreferencesGeneralTag];
- (void) buildToolBar
    _toolbarItemList = [[NSMutableArray alloc]init];
    _toolbarItems = [[NSMutableDictionary alloc] init];
    // Create Tool Bar Buttons
    [self createToobarButton : _general          : @"General"        : @"General"        : @"NSPreferencesGeneral"       : @""];
    [self createToobarButton : _registration     : @"Logging"   : @"Logging"   : @"NSPreferencesLogging"       : @""];
    _toolbar = [[NSToolbar alloc] initWithIdentifier:@"preferencePanes"];
    [_toolbar setDelegate:self];
    [_toolbar setAllowsUserCustomization:NO];
    [_toolbar setAutosavesConfiguration:NO];
       [self.window setToolbar:_toolbar];
Ok if in awakefromnib I remove [self buildToolBar]; then the view loads but obviously there is now no toolbar.
Futher more you can leave that in and remove [self.window setToolbar:_toolbar]; in the buildToolBar method which obviously stops the toolbar drawing but the view loads.
So why would drawing the toolbar stop the custom view loading even though the view method is run after the toolbar method.
Thanks
