ScriptRunner Listener to copy Parent link to new custom text field called Portfolio Parent Link

SMAtlassianMber

Due to the reporting restriction on portfolio fields we are having to copy the parent link value into a standard text field so that we can report off of parent link. Below is the start of a listener I am working on, but can't get it to work. Any suggestions? 

 

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.IssueManager
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder
import com.atlassian.jira.issue.ModifiedValue
import com.atlassian.jira.issue.index.IssueIndexingService;
import org.apache.log4j.Logger
import org.apache.log4j.Level

def log = Logger.getLogger("com.acme.LISTENER")

log.setLevel(Level.DEBUG)

def issue = event.issue as Issue

def customFieldManager = ComponentAccessor.getCustomFieldManager()
def parentLink = customFieldManager.getCustomFieldObjectByName("Parent Link")
def value = issue.getCustomFieldValue(parentLink)
def parentKey = value.key
def parentIssue = ComponentAccessor.issueManager.getIssueByCurrentKey(parentKey)
def portParentLink = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("Portfolio Parent Link")
def changeHolder = new DefaultIssueChangeHolder()
def issueIndexManager = ComponentAccessor.getComponent(IssueIndexingService)

if (parentIssue == null)
{
log.debug ("Parent link value is null: End listener")
}
else
if (parentIssue != Null)
{
portParentLink.updateValue(null, issue, new ModifiedValue(issue.getCustomFieldValue(parentIssue),changeHolder)
}
issueIndexManager.reIndex(issue)
}

What aspect of it doesn't work? If you just run the code in the console, does it work? Does it produce the correct output? Does it update the issue?
