your right, i probably should seperate the hits better.
the module that contains my make_history function i did not want to have to
create a store
for each time one of the functions operated, so i use the store of the
object that i pass into it from my main thread.
def do_some_thing_with_object( obj ):
store = Store.of(obj)
this allows me to use the store that was created in the main thread.
i will try again with renamed variables. Maybe the values are not maintained
well because of the way i have them. Since the same store had a hit in it
that represented a StatusHit and one that represented a HistoryHit.
that kinda still wouldn't explain why raw is the only one that does not get
updated.
but i am still new to a lot of this.
thanks
