Help with Scriptrunner - Parent issue not transitioning when sub-task transitions

[Alex Cumberland]

ScriptRunner 6.18.0 

Jira Server 8.13.1

The logs show no issues and displays the values that I expect but the parent stays in the "Open" status. 

The sub-task and parents use the same workflow.  The transition that I am trying for the parent is "Start Progress" (transition id = 4) which would put it in status "In Progress" (step id = 3) from "Open" or "Reopened" status.

I am using the following script that is the last step in the post-functions:

import com.atlassian.jira.bc.issue.IssueService;
import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.user.ApplicationUser;
import com.atlassian.jira.workflow.TransitionOptions;
import com.atlassian.jira.issue.MutableIssue;
import com.atlassian.jira.project.Project;

// Logging Imports
import org.apache.log4j.Level
import org.apache.log4j.Logger

log = Logger.getLogger("console") 
log.setLevel(Level.DEBUG)

def Project project = issue.getProjectObject()

Integer actionID = 4; // Transition ID value

log.debug "project key: " + project.key;
log.debug "issue key: " + issue.key;
log.debug "issue Type: " + issue.issueType.name;

// Only want to perform for sub-tasks in the OK Project
if (project.key == "OK" && issue.issueType.name == "Sub-task") {

IssueService issueService = ComponentAccessor.getIssueService();

// Get the userID that is logged in currently
ApplicationUser currentUser = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser();

// Get the parent issue object
MutableIssue parent = issue.getParentObject() as MutableIssue

// Check the status of the parent object
def isValidSubTaskStatus = parent.status?.name in ['Open', 'Reopened']

// If the parent status is valid, then we want to transition the parent
if (isValidSubTaskStatus) {
TransitionOptions transitionOptions = new TransitionOptions.Builder()
.skipConditions()
.skipPermissions()
.skipValidators()
.build()

IssueService.TransitionValidationResult result = issueService.validateTransition(currentUser,
parent.getId(),
actionID,
issueService.newIssueInputParameters(),
transitionOptions)

}

}

Figured out the issue and was a real self head smack moment.

The script is fine except it does not have a step to do the actual transition.

Needs the following Code after the Validate Transition step:

if (result.isValid()) {
     issueService.transition(currentUser, result);
   }

Doing this will then actually fire the transition on the parent.
