Class-Within-Class and Archiving

I am trying to figure out how to properly archive data involving a couple of custom classes.

I've made a custom class called "Book" and it contains a few simple NSString variables for title, author, publisher, and such. It also contains an array which is filled with another custom class called "Character." The "Character" custom class has simple NSString variables for name, age, role and so on. Before I added the array of "Character" objects to my "Book" class, I could simply use NSArchiver to save the data to a file. Now, with each "Book" object containing some "Character" objects, NSArchiver won't work. Both methods conform to NSCoding and separately they can be NSArchived just fine. But when one class contains objects of the other class, NSArchiving falls apart.

I am using an NSMutableArray of "Book" objects to serve as the datasource for an NSTableVIew. Getting all the data to display in the NSTableView works just fine, but I can't get the data to save.

My question is this: Is there a way (hopefully a simple one) to save my data in the manner in which I am currently organizing it? I've got an array of "Book" objects each of which contains some number of "Character" objects. I would like to just save the data in one file, but if two files are necessary, then so be it. Any ideas in the matter would be much appreciated. _______________________________________________ Do not post admin requests to the list. They will be ignored.
