How can I close a document that has no window?

Hi,

I have a document based app that loads docs in tabs rather than windows.  I have a subclass of NSWindowController manage the tabs.  I am confused from reading the documentation just how I should go about closing my document.  Right now I:

1) have the TabView call a method on the controller subclass that invokes the canCloseWindowCOntroller:withDelegate: ... method in my document subclass.  The callback is in the window controller and calls the window controller's close method
2) this just uses super's method and so calls the canCloseDocument:withDelegate:selector ... method which sees that the doc is closeable and calls the document's close method.  I to set the controller's doc to nil here or I get a bad access crash.
3) this method actually seems to call t he window controller's close method which deallocs the doc apparently then closes itself.

It works, but I feel like I've created a mess.  Have I?

John
