   Sure.
   If not-joined record is emitted at window-close, but there is also a 
joined-record available at that time, then both not-joined and joined would be 
emitted wouldn't they?
   In the joined-item-logic the not-joined record in the outerJoinStore is 
nullified (correctly) but it has already been emitted before.
   
   
   Or am I mistaken?
