I think this is not needed. If you do not provide any software trigger to your configurable cfgTriggerMasks, the function jetderiveddatautilities::selectTrigger will always evaluate TRUE (because there is. check in that function if the triggerMask is empty not. Please remove this configurable to avoid confusion
