Scott - thanks for this post. It has helped me a lot!

One of the things i'm stuck on is [using your example] that I can't set and then read a variable from an outside class. It keeps going back to null....

So if I set 'caption' from one method
and try to get the value that is on 'caption' from another method, it is gone. I know there is discussion above, but i'm not too sure what the resolution is.

I am using something like this to read the 'caption' value:

method1============================
photo* myPhoto = [[photo alloc]init];

myPhoto.caption=@"some caption";
NSLog(@"caption: %@",myPhoto.caption);
==================================
in this example all is well.

now in the same class I try this method and the value is now null

method2============================
NSLog(@"caption: %@",myPhoto.caption);
==================================

dude - not too sure what I'm missing. Must be part of the asp.net to objective-c cycle... arghhh..

any thoughts?
