UISplitViewController non root, forcing custom rotation methods, makes master view dissappear

Question

I'm trying to add a split view inside of a tab bar, and since the split view isn't the root, it doesn't properly get the rotation notifications, so the delegate's methods are never called to add the button to the toolbar in the detail view.

I've rigged it up so I can generate the popover when rotated, but when this method is called, the view dissappears from the landscape mode, and if you activate it and then rotate back into landscape, it's a black empty box where the master view used to be. How do I get rid of this occuring?

-(void) displayPopover:(id)sender
{
    //Toggle the popover: if it's showing, hide it
    if (popoverController != nil && [popoverController isPopoverVisible]) 
    {
        [popoverController dismissPopoverAnimated:NO];
    }
    else
    {
        //Create a Popover displaying the master view
        if (popoverController == nil)
        {
            popoverController=[[UIPopoverController alloc] initWithContentViewController:self->rootController];
            popoverController.popoverContentSize=CGSizeMake(300, 500);
    }
    [popoverController presentPopoverFromBarButtonItem:[detailController.toolbar.items objectAtIndex:0] permittedArrowDirections:UIPopoverArrowDirectionAny animated:NO];
}

You will need to remove all the objects from window using:

 [appdelegate window ] subviews] objectAtIndex:0] removeFromSuperview]; 

Then add your splitview to the window, you can get the view callbacks.
