Hello, Currently, there are two "publish" fields, one in the task(regular "publish")-the scope is branch and not global, and another under "on-success", “on-error” or “on-complete”. In the current behavior, regular "publish" is ignored if there is "publish" under "on-success", “on-error” or “on-complete” [1]. For example:- (a) version: '2.0' wf1: tasks: t1: publish: res_x1: 1 on-success: publish: branch: res_x2: 2 (b) version: '2.0' wf2: tasks: t1: publish: res_x1: 1 "res_x1" won't be published in (a), but it will in (b). We can either:- 1) Invalidate such syntax. 2) Merge the two publishes together and if there are duplicate keys, there are two options:- a) What takes priority is what's in publish under "on-success" or “on-error” or “on-complete. b) Not allow having a duplicate. What is your opinion? And please tell us if you have other suggestions. [1] https://bugs.launchpad.net/mistral/+bug/1791449
