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. 

Hi guys,


Does anyone know if the Original Estimate or Time Tracking fields can be updated with script runner?

I have searched a lot but I can't find an answer.





What if my field is a Select List? How does that change the code you've provided? 

Hi @Thanos Batagiannis [Adaptavist],

I am trying to use your groovy script for my listener
Could you help me with this error please ? 
NB : I changed issue to event.issue because I had this error : "[Static type checking] - The variable [issue] is undeclared". However, the other error was already there.

Thank you in advance,
