I'm not surprised that you ran into some issues, but I do think that the new 
interfaces will be easier to work with in the long run. I actually considered 
adding isEditing() and cancelEdit() when I first updated the interfaces, but at 
the time they didn't seem necessary. Sounds like they are, though - I'll try to 
get them in sometime later today.
