Set assignee based on custom field value

[Jimit Jhaveri]

I am having an issue where I am trying to set an assignee based on a custom field value. This current code block below shows no errors when editing and I also get no errors when running in a workflow post function. However, the assignee of the field does not change. What am I doing wrong?

import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.CustomFieldManager;
import com.atlassian.jira.issue.fields.CustomField;
import com.atlassian.jira.issue.IssueManager;
import com.atlassian.jira.issue.Issue;
import com.atlassian.jira.user.util.UserManager;
import com.atlassian.jira.issue.MutableIssue

def issueManager = ComponentAccessor.getIssueManager();
def userManager = ComponentAccessor.getUserManager();
def customFieldManager = ComponentAccessor.getCustomFieldManager();
def cField = customFieldManager.getCustomFieldObject("customfield_12400");
def cFieldValue = issue.getCustomFieldValue(cField);

if (cFieldValue == "Security") {
 def assignee = userManager.getUserByKey("i849194");
 issue.setAssignee(assignee);
}
else if (cFieldValue == "Operations") {
 def assignee = userManager.getUserByKey("i826121");
 issue.setAssignee(assignee);
}

else if (cFieldValue == "Instance Creations/Backups") {
 def assignee = userManager.getUserByKey("i825046");
 issue.setAssignee(assignee);
}

Hello,

Try to write it like this:

if (cFieldValue.toString() == "Security") {
 def assignee = userManager.getUserByKey("i849194");
 issue.setAssignee(assignee);
}
else if (cFieldValue.toString() == "Operations") {
 def assignee = userManager.getUserByKey("i826121");
 issue.setAssignee(assignee);
}

else if (cFieldValue.toString() == "Instance Creations/Backups") {
 def assignee = userManager.getUserByKey("i825046");
 issue.setAssignee(assignee);
}

Alexey, this worked! Thank you for your prompt response!

You are welcome!

Hi Jimit,

Where is this post function? In create transition or another? Also, in which order is it?

[Jimit Jhaveri]

It is the first transition after create. So the second transition. Currently this post function is at the top of the list in terms of order to follow.

I'm having a similar issue. I was going to open my own question, but I think the answer you get will be the same as the answer I need, so maybe I can contribute a bit. 

I think the problem has to do with needing to persist the data. Here's the code I'm trying to get to work:

import com.atlassian.jira.bc.issue.IssueService
import com.atlassian.jira.bc.issue.IssueService.UpdateValidationResult
import com.atlassian.jira.bc.issue.IssueService.IssueResult
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.user.ApplicationUser
import com.atlassian.jira.issue.IssueInputParameters
import com.atlassian.jira.user.util.UserManager
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.MutableIssue

log.setLevel(org.apache.log4j.Level.DEBUG)

def reviewCompletionStatusField = ComponentAccessor.getCustomFieldManager().getCustomFieldObject("customfield_10209")
def epicLinkField = ComponentAccessor.getCustomFieldManager().getCustomFieldObject("customfield_10100")
def issueType = event.issue.issueType.name

//Initial/Validation Review:
//if Not Approved, assign triage subtask to coordinator and put it into todo
//if Approved with comments or approved, assign Canada Initial Review subtask to canada contact (tbd) and put it into todo, also notify coordinator

//Approved, Approved With Comments, Not Approved

log.info event.toString()

//Only do work if the task that changed was DND Initial Review or DND Validation Review
if(issueType == "ADS Initial Review" || issueType == "ADS Validation Review"){
 log.info "Triggered by change made to issue ${event.issue}" 

 if (event?.getChangeLog()?.getRelated("ChildChangeItem")?.find {it.field == "Review Completion Status"}) {

 def newValue = event.issue.getCustomFieldValue(reviewCompletionStatusField)
 log.info "The Review Completion Status field has changed to ${newValue}"

 MutableIssue remedIssue = null
 Issue parent = event.issue.getParentObject()
 def subtaskToAssignName = "";

 switch(newValue){ 
 case "Not Approved":
 subtaskToAssignName = "Triage"
 break;
 case "Approved":
 case "Approved With comments":
 subtaskToAssignName = "Initial Review"
 break;
 }


 parent.getSubTaskObjects().each{sibling->
 if(sibling.getIssueType().name == subtaskToAssignName){
 remedIssue = sibling as MutableIssue 
 log.info "Remediation issue found: ${remedIssue.key} - ${remedIssue.summary}"
 } 
 }

 if(remedIssue != null){ 
 // Issue epic = parent.getCustomFieldValue(epicLinkField) as Issue
 ApplicationUser coordinator = ComponentAccessor.getUserManager().getUserByName("someUserName") 
 log.info "The coordinator lead for this task is ${coordinator}"
 remedIssue.setAssignee(coordinator)
 
 ApplicationUser loggedInUser = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()

 if (!loggedInUser) {
 loggedInUser = UserManager.getUserByName('jira_bot')
 }
 
 def validateAssignResult = ComponentAccessor.getIssueService().validateAssign(loggedInUser, issue.id, coordinator.getKey())
 ComponentAccessor.getIssueService().assign(loggedInUser, validateAssignResult)
 } 
 } 
}

I think the line that's giving me some trouble is towards the end:

def validateAssignResult = ComponentAccessor.getIssueService().validateAssign(loggedInUser, issue.id, coordinator.getKey())

I think I need to find a way to get the user id in string format to replace 'coordinator.getKey()'
