Okay, I think I've found the problem, but I'm not sure why it's a
problem. I had two NSArrayControllers bound to the same
NSManagedContext. I had one text view bound to the selection in the
first controller, and another text view bound to the second array
controller. I removed one of the array controllers and instead bound
both text views to the remaining one. Then, everything worked.
Is it bad to have more than one array controller bound to the same
NSManagedContext?

Is there any reason you can't write a NSString to NSData two-way

relying on something that doesn't work consistently.

Here's an odd one: I have an NSTextView bound to an attribute of a
Core Data entity of type "binary". Works fine.
However, if I go into IB and check "Continuously Updates Value" on
the NSTextView's bindings settings, subsequent runs of the program
tell me that it "Cannot create NSData from object of class
NSCFString".
It gets stranger. If I turn Continuously Updates Value" off, the
program still fails with the same error. I actually have to unbind
the text view, run the program, quit it, then re-bind with
"Continuously Updates Value" unselected to "fix" it again.
I am building this program on Xcode 3.1 (beta), compiling with GC,
if that makes a difference.
I'm at the end of my rope on trying to figure this one out. Can
anyone help?
Thanks,
Mike
