One question was solved. I found a correct keypath to bind my document on selected filter. It works with "selection.self" keypath. But my -setFilter method still doesn't get called when I change it's properties. Maybe it is right, but I need to know when filter's properties were changed. Do I need to register observer for every filter that will be set by -setFilter?
