Talk:Programming Mac OS X with Cocoa for Beginners/Document-based applications

The setting of document types doesn't work for XCode 3.2.

I can save the document, but I can't open it again, I think it has something to do with exporting types. Before I set the options, everything works fine!

Actually I mistook the identifier for the UTI, and that lead to my peril, on the other hand, I read throught the Xcode docs! :)
