Important: Subclasses must invoke super’s implementation before
performing their own initialization.
I just moved the snippet below the super call and changed it to:
Log(@"------------------------------");
Log(@"(self title=%@) awakeFromFetch", [smart title]);
NSSet* relationship = [smart sourceContainers];
Log(@"Class=%@, non-nil=%@", NSStringFromClass([relationship class]),
relationship ? @"YES" : @"NO");
for(EBContainer* source in [smart sourceContainers])
Log(@"(self title=%@) source title=%@", [smart title], [source title]);
In what sense is the relationship not restored properly? Are you
simply seeing faults?

The relationship shrinks (ie the NSSet contains less objects after
fetch than it did on save). The example below shows the following loss:
- AllSmart loses the pointer to Reddit
- RedditOne loses the pointer to Reddit
On application quit (after context save):
