Subtask assignee are not modified on listener

Hi, I need to update subtasks assignees of issue to "Project Manager" when "Project Manager" field is changed.

I've made a Listener on IssueUpdate with the following script:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.event.issue.IssueEvent
import com.atlassian.jira.event.issue.field.AbstractCustomFieldEvent
import com.atlassian.jira.issue.changehistory.ChangeHistoryManager
import com.atlassian.jira.event.type.EventDispatchOption
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.IssueManager

ChangeHistoryManager changeHistoryManager = ComponentAccessor.getChangeHistoryManager()

def issue = event.issue

if (issue.getIssueType().getName() == "Purchase Order") {
def changes = changeHistoryManager.getChangeHistories(event.issue)
def change = changes.last()

for (i in change.getChangeItemBeans())
if (i.getField() == "Project Manager"){

def user = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()

def subTaskManager = ComponentAccessor.getSubTaskManager()
IssueManager issueManager = ComponentAccessor.getIssueManager()
def userManager = ComponentAccessor.getUserManager()

Collection subTasks = issue.getSubTaskObjects()

for (s in subTasks) {
def subtask = issueManager.getIssueObject( as MutableIssue;
if (i.getTo() != null) {
def assignee = userManager.getUserByKey(i.getTo())
issueManager.updateIssue(assignee, issue, EventDispatchOption.ISSUE_UPDATED, true)

The listener ends ok, and from the log I could check that the subtask are correctly detected, and also is assignee, but when I check the subtasks assignee value has not been changed.

Any one could detecte the incident?

This line

issueManager.updateIssue(assignee, issue, EventDispatchOption.ISSUE_UPDATED, true)

Is attempting to save the source issue rather than the subTask

Change it to

issueManager.updateIssue(assignee, subtask, EventDispatchOption.ISSUE_UPDATED, true)
