Adaptavist Scriptrunner: Update Custom Field Value of all Outward Links, Listener

[Judah]

I need to update a custom field's value on all the child issues (feature issues) that are connected to a project, so that they match their parent whenever it (the project issue) is updated. 

I have been able to access all of the child issues of my given project.  My second 'log.debug' below returns a List (array?) of the children issues linked to the project 'DEVP'...

I need automatically update a custom field on ALL of these children issues when that same field is updated on the parent...

if (issue.projectObject.key == "DEVP"){
 
 log.debug (issue)
 log.debug (issueLinkManager.getOutwardLinks(issue.id))

//field.updateValue(null, issue, new ModifiedValue(issue.getCustomFieldValue(field), field), changeHolder)
 
}

Can I implement updateValue() multiple issues at once? Do I need a loop?

Entire script: 

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.issuetype.IssueType
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder
import com.atlassian.jira.issue.IssueInputParameters
import com.atlassian.jira.issue.ModifiedValue
import com.atlassian.jira.bc.issue.*
import static com.atlassian.jira.workflow.TransitionOptions.Builder;
import com.atlassian.jira.issue.IssueManager;
import com.atlassian.jira.issue.link.IssueLinkManager
import com.atlassian.jira.issue.link.IssueLink
import org.apache.log4j.Logger
import org.apache.log4j.Level


MutableIssue issue = ComponentAccessor.getIssueManager().getIssueObject("DEVP-384"); 
IssueLinkManager issueLinkManager = ComponentAccessor.getIssueLinkManager();

def changeHolder = new DefaultIssueChangeHolder()

def customFieldManager = ComponentAccessor.getCustomFieldManager()
def issueManager = ComponentAccessor.getIssueManager();

def field = customFieldManager.getCustomFieldObjects(event.issue).find { it.name == "Issue Category" }
 
def issueService = ComponentAccessor.getIssueService()
def user = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()

def issueCatValue = issue.getCustomFieldValue(field)

def log = Logger.getLogger("com.acme.CreateSubtask")
log.setLevel(Level.DEBUG)

if (issue.projectObject.key == "DEVP"){
 
 log.debug (issue)
 log.debug (issueLinkManager.getOutwardLinks(issue.id))

 //field.updateValue(null, issue, new ModifiedValue(issue.getCustomFieldValue(field), field), changeHolder)
 
}

 I can access my Custom Field, the Project, and all of it's children...but I am having trouble putting these parts together. Thank you.

As far as I know, you need a loop.

At least updateValue method expects single Issue as a parameter.

[Judah]

Yes you are correct. A loop was necessary, as I needed to access each linked issue singularly and then update the field.

@Judah would you mind sharing your final code? I need to do something similar.  Thanks so much!

@Katrina Thacker For some reason this script is no longer in production and I cannot locate it. But this script is similar in that it defines some custom fields and sends changes down the chain when the parent field is updated
