NSImageView redraws

Hi all,

I have an issue where an NSImageView only updates the NSImage it is displaying if it is scaling the NSImage down to fit.

The NSImage is backed by an NSBitmapImageRep which is being modified via a slider. After each modification I am calling

[imageView setImage: nil];
[imageView setImage: image];

to update the view. Caching is turned off in the NSImage and retainData is set to YES.

The view is being redrawn (I can see this using Quartz Debug), but it appears a cached version of the image is being used.

What am I doing wrong?

Thanks,

Chris
