I have a Core-Data Document app that I am trying to have instantiate an object when opening a new document. I have gotten this part to work by checking for this objects existence during awakeFromNib by using executeFetchRequest; If the object does not exists, then I create one using insertNewObjectForEntityForName. This works fine with the exception that it dirties the document, and can be "Undo"ne.
