I did a rewrite, based off our internal code here: https://github.com/karelia/BSManagedDocument Read through the header for full details, and make sure you work with the ksmanageddocument branch for now.

Re: Using a document bundle file type with core data
Thank you! I will take a closer look at that soon. If you have a quick answer as to how I can have the -fileWrapperOfType:error: method be called, I would be interested.

Re: Using a document bundle file type with core data
The code in this blog article enables saving core data files to a package: http://cutecoder.org/featured/asynchronous-core-data-document/ Take a look at the writeSafelyToURL implementation in the gist at the bottom. I haven't tried saving to a bundle myself, but found the article helped me solve some problems with core data and documents.

Using a document bundle file type with core data
I've got a sample project at: http://ericgorr.net/cocoadev/docbundleCD.zip Basically, what I am attempting to do should be fairly standard and simple, but I am apparently missing something obvious. I only want to be able to define my document type as a document bundle and place a Core Data file inside. Clearly, my sample project is incomplete, but the start of any such project would require that the -fileWrapperOfType:error: method be called and it isn't despite the fact that I have set LSTypeIsPackage to YES for my document type - which is what I have done in the past for situations such as this, but they did not involve Core Data. Any thoughts? If there are any sample projects or tutorials, I would be interested as well.
