How to update user custom field value

[Madhusudhan Matrubai]

Hi There,

I'm trying to update custom field of type "User" and somehow it's not working for me and no errors either.

import com.atlassian.jira.ComponentManager 
import com.atlassian.jira.component.ComponentAccessor 
import com.atlassian.jira.issue.CustomFieldManager 
import com.atlassian.jira.user.util.UserManager 
import com.atlassian.jira.user.ApplicationUser 
import com.atlassian.jira.issue.fields.CustomField 

CustomField itManager = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("IT Manager") 
ApplicationUser itManagerUser = ComponentAccessor.getUserManager().getUserByName('popeye') 

issue.setCustomFieldValue(itManager, itManagerUser);

I have found the workaround, just in case someone is looking for a similar solution. 

import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.ModifiedValue
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.user.ApplicationUser

def changeHolder = new DefaultIssueChangeHolder()

def itMgrField = ComponentAccessor.customFieldManager.getCustomFieldObjectByName("IT Manager") 
def itMgrTargetFieldValue = issue.getCustomFieldValue(itMgrField) 

ApplicationUser itMgrSourceFieldValue = ComponentAccessor.getUserManager().getUserByName('popeye') 
itMgrField.updateValue(null, issue, new ModifiedValue(itMgrTargetFieldValue, itMgrSourceFieldValue),changeHolder)

Perhaps this is because setCustomFieldValue does NOT write your changes to the database and thus you have to update your issue after calling this method. 

Try adding this to your code:

import com.atlassian.jira.issue.UpdateIssueRequest

ApplicationUser currentUser = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()
ComponentAccessor.getIssueManager().updateIssue(currentUser, issue, UpdateIssueRequest.builder().build())

Or put the post function first in the list of post functions

Thanks @Ivan Tovbin and @Alexey Matveev for your prompt help here.

Unfortunately the above suggested workaround did not help me.
