Update Custom Field Value using a “ScriptRunner for Jira” Custom Listener

I have a list of custom fields in sub-tasks that need to be update automatically whenever the associated field is update in the parent.  The fields are the same from parent to sub-task

PO Number (Parent) to PO Number (Sub-task)

Tracking Number (Parent) to Tracking Number (Sub-Task)

Vendor Name (Parent) to Vendor Name (Sub-Task)

Vendor Contact Name (Parent) to Vendor Contact Name (Sub-Task)

Vendor Email (Parent) to Vendor Email (Sub-Task)

Any time any one of those fields are updated in the parent i need it to be updated across all of the sub-tasks. 

Can someone help me write this listener?

Hi Scott, 

What it really matters when trying to update a custom field is the type of it. From your description I can understand that the fields you want to update are going to be either a TextField or a Number Field. 

So as you said you will need a listener listening for an issue updated event. 

The script for this listener should be similar to 

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.ModifiedValue
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder

// Check it the update that just happened is because of "TextFieldA" or "Number CF"
def change = event?.getChangeLog()?.getRelated("ChildChangeItem")?.find {it.field in ["TextFieldA", "Number CF"]}

//the change is not in one of the fields we are interested in or the issue has not subtasks - do nothing
if (!change || !issue.subTaskObjects) {

issue.subTaskObjects?.each {
syncCustomFieldValue(issue, it, change.field)

* Sync the value (update childIssue value according to parent's issue one)
* @param parentIssue
* @param childIssue
* @param fieldName
def syncCustomFieldValue(MutableIssue parentIssue, MutableIssue childIssue, String fieldName) {
def changeHolder = new DefaultIssueChangeHolder()
def cf = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName(fieldName)
def newValue = parentIssue.getCustomFieldValue(cf)
cf.updateValue(null, childIssue, new ModifiedValue(childIssue.getCustomFieldValue(cf), newValue), changeHolder)
log.debug "Field $fieldName updated"

Hope that helps, 



That worked great! Thank you so much. How do i get it so it updates across all sub-tasks and not just the first?

Hey Scott, 

That's great. I updated the script above to make the update to all the subtasks.

Wow that was it?!?!  Crazy. It works perfectly. Thank you.
