cannot delete shouts with PARTIALEXECUTION

[Thomas Radons]

I am not able to delete a Shout which was partly executed. If a shout was partly executetd I also want to delet the restQuantity of the shout.
In code I tried this:

def onOrderStatusUpdateReceived(Shout shout, GPathResult gpathSource) {
    log.info "Shout received: ${shout.shoutID} - with Mod ${shout.modReasonCode}"

    if(shout.modReasonCode==ModReasonCode.PARTIALEXECUTION){
      log.info "partialExecution $shout.shoutID"
      submissionService.deleteShout(shout)
    }

I do not receive further OrderStatusUpdates with this shoutID (Expected was an OrderStatusUpdate with DELETIONBYUSER)
