Hi Alex, Found it! Well, Jean-Daniel did - Thanks again!
I was barking up the wrong tree thinking it was the back links that were the problem. Using weak caused them to (correctly as it turned out) be set to nil when the node it reference is released. The problem was in the initWithCoder method, I was using: self.pNetworkNodeChildArray = [[NSMutableArray alloc] initWithArray:myArray copyItems:YES]; and that should be - copyItems:NO I’m not sure where I got the YES from, I think it was from a very simple example I found online. Anyway if you set it to NO, it works as expected. Worth checking if you have this too when you shouldn’t. AFAIK, there are no working examples of using a back link like this, if anyone wants to post my sample code to their web-site they are welcome to it, just drop me a line.
