Re: NSDocument/NSFileWrapper troubles: solved

Problem solved, thanks for the help, all. It was a combination of two retain problems - first, the stray [wrapper release] down in windowControllerDidLoadNib, and the second, accidentally releasing an autoreleased object deeper into my methods.

All in all, just another lesson that memory management's of the utmost importance in Cocoa.

I'm having troubles with some NSDocument code that I, a Cocoa newbie, wrote. I'm trying to preserve an NSFileWrapper passed by loadFileWrapperRepresentation:ofType: within the NSDocument. If I create a new file, I can save it, even multiple times, and all's well and good. However, when I load a file from disk and try to save it again, my application crashes.

If I comment out my "wrapper = newWrapper" line in loadFileWrapperRepresentation, the application runs and saves, albeit without loading any of the data. This looks eerily like a simple retain problem, but if it is, my newbie eye certainly can't find it.

I sliced the detailed pieces for loading and saving out of the routines. What's left is enough to cause the crashing behavior when saving files, which actually occurs after the loading/saving is complete during the event loop, not anywhere that's easily >> debuggable.
