Need to create sub-tasks based on multiple select list custom field Edited

Hello ,


We have custom field states with multiple selection our requirement is when they select 4 states four sub-tasks has to be created.

Kindly help me with script by using built in create sub-task post function i'm able to create only one sub-task.

Note : That multiple custom field data is coming from Database through Elements we have configured that 

We need custom script post function when multiple values are selected that number of sub-tasks has to created

Hi @Mahesh Kallepalli 

I would like to suggest you try Automation for JIRA plugin. You can simply customize the automation below to achieve your need:

Here's the background of the rule configured below

- A custom field with two possible options (Option 1 and option 2)

- The rule is triggered every time the custom field is changed

I have achieved this through automation but my client is using only script runner they don't want to buy Automation plugin .

Have a look at - there are several "create sub task" scripts there.

We written this code in custom script post function but only one sub-task is creating randomly based on selection , Could you please help us on this.

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.customfields.option.Option
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.MutableIssue

import groovy.json.JsonSlurper

Issue parentIssue = issue
if (parentIssue.getIssueType().getName() == 'Sub task')

def cfState = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("State - Multi Select")
MutableIssue issueObject = ComponentAccessor.issueFactory.getIssue()
String statesString = (String) issue.getCustomFieldValue(cfState).toString();
JsonSlurper slurper = new JsonSlurper()
Map parsedJson = slurper.parseText(statesString) as Map;
List states = parsedJson.get("keys") as ArrayList;
if(states != null && issue.getIssueType().getName()=='RFP'){

for (int i = 0; i < states.size(); i++) {

def issueManager = ComponentAccessor.getIssueManager()
def subTask = issueManager.createIssueObject(ComponentAccessor.jiraAuthenticationContext.getLoggedInUser(), issueObject)
ComponentAccessor.subTaskManager.createSubTaskIssueLink(issue, subTask, ComponentAccessor.jiraAuthenticationContext.getLoggedInUser())
