From d71b4e3cc240e350ff146554b3f3d8399d03a669 Mon Sep 17 00:00:00 2001 From: Jim Hahn Date: Mon, 24 Feb 2020 10:38:07 -0500 Subject: Add "finalOutcome" flag to OperationOutcome The Actor clients receive notifications of operation failures, but no indication if it's the final failure, thus they do not know if they should progress on to the "failure" policies.
