Re: PubSub, enclosures and "Couldn't find PSFeed of PSEntry"

Now it's getting weird!

Let me recall the problem, the following code does *not* work:

- (void)downloadStateDidChanged:(NSNotification *)notification {
   PSEnclosure *enclosure = [notification object];
   PSEntry *entry = enclosure.entry;
   NSLog(@"%@", entry.feed);
}


While I was looking for a workaround, I found that the following code 
does work:

- (void)downloadStateDidChanged:(NSNotification *)notification {
   PSEnclosure *enclosure = [notification object];
   PSEntry *entry = enclosure.entry;
   PSEntry *iDontUseThisVariable = [[PSClient applicationClient] 
entryWithIdentifier:[entry identifier]];
   NSLog(@"%@", entry.feed);
}


So calling the entryWithIdentifier method does some internal stuff so 
that our entry automagically gets its feed back! To remove the 
compiler warning about the unused warning, simple ignore the object 
returned by the method by just calling "[[PSClient applicationClient] 
entryWithIdentifier:[entry identifier]];".

I guess I should fill a bug report for this.
