I've created some key-value bindings through IB to connect an

I set up the valueURL of the myImageView as
myArrayController.selection.URLToPDFFile.
Now I'm trying to use drag and drop of a file from the Finder to set
this value. The drag and drop code is in myImageView. Here's a snippet:
I always get the following error when I try the drag and drop:
[<myArrayController 0x345310> setValue:forUndefinedKey:]: this class is
not key value coding-compliant for the key selection.URLToPDFFile
Shouldn't it be key-value compliant if I set up the bindings in IB?
Umm, no, you have to implement the appropriate methods...

Or am I just completely missing the point?
I think you are; you'll probably need a value transformer to convert
the url...
