Hey Jack -
That means that either the outlet isn't connected, or the NIB hasn't
been loaded yet when setImage: is called.
Also, are you sure you aren't creating more instances of your class
than you think you are? A common mistake is to instantiate the class
in code, and tell it to load a NIB, but the NIB file also instantiates
a second instance of the class because the File's Owner was
misunderstood.
Hope that helps -

The result is null.

What happens if you include this log to your setImage method?
NSLog(@"image view: %@", boxPic);
Also, rather than logging you should see if you can find the time
to learn to use the debugger. It's much more efficient than printf
debugging.
Good Luck -

100% certain it is connected in the xib.

connected it, then changed the name of the outlet in Xcode?
That's the output you would see if the outlet were null.

I am simply trying to set an NSImageView to an NSImage. I'm
certain i'm doing the right methods, but alas, no images show.
Suggestions ?
Thanks in advance.

boxPic is an IBOutlet connected to the NSImageView in the NIB.
-(void)setImage:(NSImage *)newImage;
{
NSLog(@"Incoming image: %@", newImage); // verifies that i am
getting an image
[boxPic setImage:newImage];
NSLog(@"%@", [boxPic image]); // gives (null)
}
