copy field value from parent to child using listeners on issue updated

Uday Kiran Raparthy

i am trying to copy custom field value from parent to all child issues and using the below code 

 

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

def issue = event.issue
def field = ComponentAccessor.getCustomFieldManager().getCustomFieldObject('customfield_13202')
def parentMyFieldValue = issue.parentObject.getCustomFieldValue(field)
def changeHolder = new DefaultIssueChangeHolder();
field.updateValue(null, issue, new ModifiedValue(issue.getCustomFieldValue(field), parentMyFieldValue),changeHolder);

 

getting error as below

Hi @Uday Kiran Raparthy 
I think your code is correct, but something else is causing the problem.

This is where the null pointer happens
def parentMyFieldValue = issue.parentObject.getCustomFieldValue(field)

field is null, so it was never assigned in the previous line.

def field = ComponentAccessor.getCustomFieldManager().getCustomFieldObject('customfield_13202')

Is that the correct customfield id ? 
You can also try with getCustomFieldObjectByName("Your Custom Field Name") to see if you get the same error. 

If you do, I think your customField is not present in that project or in that particular issue type.

Hope this helps you.
