Event monitoring generate alswas transaction.rollback with Excp in case of an error.

In some cases, for instance with the MQInput node, there is no transaction.rollback event emitted when the flow fails. When there is a validation error detected in the MQInput node (validate content and value with parse timing complete) there is a transaction.start event generated together with an transaction.end event with an empty exceptionlist.
Expected was a transaction.rollback with an exceptionList. Transection.end should only be emitted when a flow is successfull..

    RFE Review. Apologies for the length of time this RFE has been in the status of Under Consideration. We have checked this behaviour on the latest release of the product technology, ACEv11. In this situation, the input message fails validation within the MQInput node, so no transaction.rollback event is ever needed (unlike if a failure occurred in a downstream node of the flow). If you wire the failure terminal of the MQInput node, and also turn on events for propagation from that terminal, then you will receive three events ... transaction.Start, Failure.terminal, transaction.End ... So - the product does provide a means of getting hold of the exception list reflecting the validation failure.
    That said, the RFE expresses disappointment that the Exception List is not available in the transaction.End event. This would be potentially possible, but would need to be a behaviour behind a new property flag as a non-default option in order to avoid breaking anyone relying on the current product behaviour. Given the existence of a serviceable workaround, and the low number of votes (1 vote since 2013) we are unlikely to progress this RFE into the product any time soon, but we will continue to monitor it. Status of the RFE is updated to Uncommitted Candidate.
