"""hooks/on_after_flush
This hook is completely similar to 'after-flush' signal, but is meant to be
defined in a separate class so that it's easier to propagate validation hooks
to a spawned child (RecordInMask)
Open a mask right clicking on a record, change something and save. You'll see
that on_after_flush is called eather.
