Listener - Setting assignee based off Component Lead

[patricia_scott_honeywell_com]

I have a custom scriptrunner listener that checks if the Components field was updated, and if it was retrieve the Component lead for the first component in the list.  Then I want it to set the assignee to that component lead.

I know it is retrieving the component lead correctly, but the script is not setting the assignee as expected and I am not sure why.

I must be missing something, can someone help me know what I am doing wrong?  Here is my code:

import com.atlassian.jira.event.issue.IssueEvent;

import com.atlassian.jira.issue.CustomFieldManager;

import com.atlassian.jira.issue.fields.CustomField;

import org.ofbiz.core.entity.GenericValue;

import com.atlassian.jira.user.ApplicationUser;

import com.atlassian.jira.user.util.UserManager;

def int icount = 1

def String DefaultAssignee = ""

// Checking if the "Components" field value has changed.

def event = event as IssueEvent;

def changeHistoryManager = ComponentAccessor.getChangeHistoryManager();

def issue = event.getIssue() as MutableIssue;

def changelog = event.getChangeLog();

def changedFields = findFieldsMentionedInChangeLog(changelog)

// Component field has changed, then set the Component Lead as the Assignee

if (changedFields.contains("Component")) {

    // def String ComponentName = issue.components.name

    def String ComponentDefaultAssignee = issue.components.lead

    def ilength = ComponentDefaultAssignee.length()

    // If Component has multiple values, retrieve the Lead for the first component.

    if (ilength > 0) {

        while (icount <= 7) {

            DefaultAssignee = DefaultAssignee + ComponentDefaultAssignee[icount]

            icount = icount + 1

        }

        // Find the user name for the user to set as the assignee

        def user = ComponentAccessor.userManager.getUserByName(DefaultAssignee)

        // Set the assignee field to the component lead

        issue.setAssignee(user)

        issueManager.updateIssue(user, issue, EventDispatchOption.DO_NOT_DISPATCH, false)

    }

}
