Hi,

After fighting a bit with my specs, I realized the bug lived in my Observer, precisely in it's after_save method:

def after_save(obj)
binding.pry
do_something if obj.status == "foo"
end

Basically, within debugger:

One the one hand:

obj.status
#=> "bar"

On the other hand:

parent = obj._root.reload
reloaded_obj = parent.children.where(:_id => obj.id).first
reloaded_obj.status #=> "foo"

I conclude, that my embedded obj doesn't bear it's updated values within my the{{ after_save}} method in the Observer.

My configuration is:

• rails '3.0.10'

• mongoid '2.2.4'
