What is going wrong? The stack trace doesn't explain that...

Thanks for your comment. I tried your suggestion to no avail.
Furthermore it is indeed NSKeyedUnArchiver that is calling dealloc as per the stack (see below).
I am quite willing to admit that I am not handling memory correctly.
However I still do not see where that is the case - probably because of my newbie ignorance.
Please be patient with me....

respect....

Hello...

Actually, I don't think it is a problem with NSKeyedUnarchiver at all. You probably just need to retain the unarchived object in your loadDataRepresentation:ofType: method... (and check to make sure you release it in your document's dealloc method).

passwordRecords = [[NSKeyedUnarchiver unarchiveObjectWithData:data] retain];


Hope that helps,

Louis
