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)
}

I figured out what was wrong and I have updated the script. now it is working.

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.ParentLinkLISTENER")

log.setLevel(Level.DEBUG)

def issue = event.issue as Issue

log.debug "Test Debug"

def customFieldManager = ComponentAccessor.getCustomFieldManager()
def parentLink = customFieldManager.getCustomFieldObjectByName("Parent Link")
def parentLinkValue = issue.getCustomFieldValue(parentLink)
def portParentLink = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("Portfolio Parent Link")
def changeHolder = new DefaultIssueChangeHolder()
def issueIndexManager = ComponentAccessor.getComponent(IssueIndexingService)

if (parentLinkValue == null) 
{
log.debug "Parent link is null: End of Script"
} 
else
{ 
log.debug "Parent link used: Update Porfolio Parent Link" 
log.debug("Child Issue = " + issue) 

def key =(String)parentLinkValue.getKey(); 
def summary =(String)parentLinkValue.getSummary(); 

log.debug("Parent Link = " + parentLinkValue + summary)

portParentLink.updateValue(null, issue, new ModifiedValue(issue.getCustomFieldValue(portParentLink),key + " "+ summary),changeHolder) 
}

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?
