I can't convert an image on disk to a NSData object and store the
data in my Core Data model.

I have a Core Data application where one of the entities has a data
attribute which I use to store an image. In the UI, the image is
displayed in an image view with bindings and an data unarchiver
formatter. If I drag and drop an image into the image well,
everything works fine.

My model class also has a method to receive the URL to an image and I
am trying to create the data object from the incoming URL without any
luck. I have tried dataWithContentsOfURL, creating an image and
converting that to a data object, but I always get the same error
when I set the data object to my model: +[NSUnarchiver
unarchiveObjectWithData:]: extra data discarded

Any help greatly appreciated. I tried on Apple's Cocoa list with no luck.

Can you supply any of your code?

Absolutely, it is quite simple.

This is my code:

-(void)setImagePathNSURL *)path {
NSLog([path className]); //just to check that I am actually getting a URL (could come from an AppleScript)
NSData *data = [NSData dataWithContentsOfURLath];
[self setValue:data forKey:@"image"];
}

The unarchiving error occurs when trying to display the image in an image view in the UI.

If I drag and drop the image on the image view, everything works fine.
