How to use transition in the Scriptrunner Separation of Duties script?

[Jason Rittenhouse]

I currently am using Scriptrunner's provided script for separation of duties found here: https://docs.adaptavist.com/sr4js/latest/features/workflows/conditions/built-in-conditions/simple-scripted-condition (script below).

The problem is that this script uses status where I want to use a transition.  I tried changing it from status to transition in the script and while the script didn't give an error, it didn't work either.  My end goal is a workflow condition that will not show the transition to the current user if a specific previous transition was used by that user.  That way the person doing the work can't also approve the work.

The original script is:

import com.atlassian.jira.component.ComponentAccessor

def changeHistoryManager = ComponentAccessor.getChangeHistoryManager()
def currentUserKey = ComponentAccessor.getJiraAuthenticationContext().getUser()?.key

// returns true if there are no transitions to the target state by the current user
!changeHistoryManager.getAllChangeItems(issue).find {
    it.field == "status" &&
        currentUserKey == it.userKey &&
        "Resolved" in it.toValues.values()
}

The answer, in case anyone else has this use case, is to check for the "from" status as well as the "to" status, like this:

it.field == "status" &&
currentUserKey == it.userKey &&
"In Progress" in it.fromValues.values() &&
"Resolved" in it.toValues.values()
 

In this example, it's checking for any transition from "in progress" to "resolved".
