I do the same thing in my app, so I had to figure it out myself. Here's
how I handle it... In your app delegate class, add these methods:


- (IBAction) askCreateNewFile:(id)sender
{
   if ([self shouldOpenNewDocument] == YES)
       [NSApp sendAction:@selector(newDocument:) to:nil from:sender];
}

- (BOOL) shouldOpenNewDocument
{
   newDocumentController = [self newDocumentController];
   NSWindow* dialogWindow = [newDocumentController window];    [dialogWindow
center];
   [dialogWindow makeKeyAndOrderFront:self];
   int resultCode = [NSApp runModalForWindow:dialogWindow];
   [newDocumentController close];

   return (resultCode == NSRunStoppedResponse) ? YES : NO;
}

- (YourNewDocController*) newDocumentController
{
   if (newDocumentController == nil)
       newDocumentController = [[YourNewDocController alloc]
initWithWindowNibName:@"YourNewDocNibFile"];

   return newDocumentController;
}

Add the shared controller member variable to the class. Then in your
MainMenu.nib, redirect the "New..." menu item to "askCreateNewFile:",
and you're done.

Hope this helps...
