When I run the application created, the document window appears, with

saved, as the red window close button has the dark dot in the middle.
If I type into each text field, then press Apple-Z to undo, the two
fields clear in turn, and then they become disabled with "No
Selection" written in them.
When you manually create object, you have to clear the undo manager,
this will clear the "needs to be saved" indicator, and will also
prevent undo from deleting the object.
See step 5 on this page, although going through the whole tutorial is
probably a good idea:
