I’m getting a weird experience in my document-based application while doing something that I thought surely would have been accounted for automatically by the document architecture. Namely, saving (or renaming) a document overtop of an existing document which is also open in the app.
Say I start my app, create a new document, make some edits, and save the document. Then, while leaving that document open, I create a second new document, make some changes, and then save it… overtop of the first document. I get the standard prompt that a document with the same name already exists — I choose “Replace”. The prompt sheet goes away, the title bar of the second document changes to reflect the saved name… and then it’s beach ball time. The app is dead. The same thing happens if I save the second document by renaming it via the window’s title bar to the same name as the first saved document. Again, I get the “Replace?” prompt, and then the app hangs. I’m surprised the document architecture doesn’t account for this scenario — where a user renames or saves a document over top of an existing document that happens to also be open in the application, in a different window. I tried doing the same thing in Pages 5.1 and Numbers 3.1, and both of them handle it by silently closing the first document once the user confirms they’d like to replace the existing document. The TextEdit sample app suffers the same hanging behavior that my app exhibits. I take it this is something I need to write code to deal with manually? Or is there something in the document architecture that I’m missing that will help me deal with or otherwise avoid this problem?
