During one of my projects I noticed in my counts that I am missing records.
As you can see 16k entries enter the requester eand only 13k exit via either port. This is connected to missing keys entering into the requestor
I know that I can solve this using a nullattributemapper to change missing into null, or by setting reject null and missing keys to 'Yes' (non-default setting). However the fact that this is largely invisible has me worried.
I have also concluded that this behaviour is not consistent. The below workspace has a test setup testing for the behaviour with simple input data. All 4 cases behave as expected. Unless I missed something, I believe this is a bug. If you can confirm, deny or reproduce, it would be highly appreciated :).
