Map a specific custom field option for cloning an issue

[Ivan Tovbin]

Hello everyone!

I'm trying to write a scripted post-function that will clone the current issue. So far, with my limited programming skills I've managed to put the following together:

import com.atlassian.jira.component.ComponentAccessor

def cfMgr = ComponentAccessor.getCustomFieldManager()
def issueSvc = ComponentAccessor.getIssueService()

def cf = cfMgr.getCustomFieldObject(12504)
def cfMap = [:]
cfMap.put(cf,Optional.of(true))
def currentUser = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()
def cloneVld = issueSvc.validateClone(currentUser, issue, issue.getSummary(), true, false, false, cfMap)
issueSvc.clone(currentUser, cloneVld)

This clones the issue including a custom field 12504 and all its present values as per the original issue. Thing is, 12504 is a check-box type custom field and it has, say 3 options ticked in the original issue. Now I would like the clone to have this field but only with, say one of the options ticked. 

Please advise if there's a way to achieve this and how?

Cheers,

Ivan
