Don't do this. Bindings really don't understad mutable value types like NSTextStorage. This is going to call -setFoo: on your managed object, which will fire KVO, which will call -setString: on your NSTextView, which will reset the cursor position.
Instead, treat the NSTextStorage as your in-memory model and only push to HTML as late as possible (probably during save).
