The way the status of an Alert Message is processed is this:
1.- If the alertStatus property of the original alert message in UCS is other than "Pending" or "Acknowledged", the processor will fail. The incoming flowfile is redirected to REL_STATUS_MISSMATCH (using UCSCreateException.routeFlowFileToException())
2.- If the alertStatus property of the new alert message is other than "Acknowledged", the processor will fail. The incoming flowfile is redirected to REL_STATUS_MISSMATCH (using UCSCreateException.routeFlowFileToException())
3.- If the alertStatus property of the new message is different than the alertStatus property of the original message, the property in the original message is updated. Use REL_SUCCESS. The message is updated in UCSControllerService by invoking updateMessage().
4.- If the alertStatus property of the new message is equals to the alertStatus property of the original message, the flowfile will be directed to a REL_NO_UPDATE relationship.
