Hello All,

I apologize in advance for such a newbie question.
Why do objects created with convenience methods get auto-released when I add them to a collection?

This simple example from the init of an NSOutlineView datasource:

[rootNode setObject:[NSArray arrayWithObjects:devices,folders,playlists,nil] forKey:@"children"];

 The array will be released before the first time I call

[rootNode objectForKey:@"children"]

If I use [[NSArray alloc] initWithObjects:devices,folders,playlists,nil] then it works fine.

Thanks,
-ryan
