Pop-up cells have a binding named "content." Text fields do not; they have "value." The full error message named the class that didn't have the key; it would clue you in to what kind of object was having the problem, and narrowed your search away from your model objects.
How did you change the column cell's class? By dragging the new cell into it, or by changing the class in the identity inspector? Don't do the latter (unless you're setting a custom subclass of what's already there).
