I am using BatchTmLeveragingStep for batch leveraging. I am missing events if the batched events are more than the BATCH_LEVERAGE_MAX constant defined in the class.
Digging thru the source code, looks like the handleEvent(Event) method ignores the Event returned from the handleTextUnit() method and always returns NOOP_EVENT. This will be an issue if handleTextUnit() returns a MultiEvent. It will be lost.
