Groovy: how to get list of users with spaces

Ivan D_qf786s

Hello,

There is the multi-user field Specialists. It's necessary to add its list items separated by comma and space, to the Summary via a post-function..

The following script gives the exception:

java.lang.NullPointerException

import com.atlassian.jira.issue.Issue;
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.user.ApplicationUser
import com.atlassian.jira.user.util.UserManager
CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager()

def cField = customFieldManager.getCustomFieldObject("Specialists")
ApplicationUser user = issue.getCustomFieldValue(cField) as ApplicationUser
cField.each {

summary.add(user + " ")

}

What's wrong with it?

Hi @Ivan D

I've tried the below script on the console and works fine. I've deleted the dedicated issue variable pointing towards a single issue, and I think that it would do the trick:

import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.IssueManager
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.event.type.EventDispatchOption

def cfmanager = ComponentAccessor.getComponent(CustomFieldManager)
def issueManager = ComponentAccessor.getComponent(IssueManager)
String summary = issue.getSummary()

def user = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()
def cFieldObj = cfmanager.getCustomFieldObjectByName("Specialists")
def mySize = issue.getCustomFieldValue(cFieldObj).size()

for (int i = 0 ; i < mySize; i++){
   summary = summary + ", " + issue.getCustomFieldValue(cFieldObj)[i]
}

issue.setSummary(summary)
issueManager.updateIssue(user, issue, EventDispatchOption.ISSUE_UPDATED, false)

Hi @Ivan D ,

if the field is multi-user, you will get list of users, so you should work with the field like this:

def cField = customFieldManager.getCustomFieldObject("Specialists")
List<ApplicationUser> users = issue.getCustomFieldValue(cField) as List<ApplicationUser>
if (users && users.size() > 0) {
    users.each {ApplicationUser user ->
        // continue here with getting user name...
}
}

Hi Alex,

Thanks a lot, it works. However for some reason it puts usernames twice: as username(username in brackets) like user1(user1), user2(user2) etc. Can full names be used instead and once?

Also can the script be modified for using in behaviours?

Ivan D_qf786s

Hi Hana,

Thanks for the feedback. However the script still returns

java.lang.NullPointerException

Also can you please specify the part

// continue here with getting user name...

Will this be working?

summary.add(user + " ")

Hi @Ivan D

Just place .getName() after the issue.getCustomFieldValue(cFieldObj)[i] :

issue.getCustomFieldValue(cFieldObj)[i].getName()

Why you want to place it on the behavior? I mean, what is the exact business requirement, and how to you want it to work?

Ivan D_qf786s

Hi Alex,

Thank you a lot, it's fixed the issue.

Actually the use case is that - now there is the behaviour that takes a current user to the summary .

import com.atlassian.jira.component.ComponentAccessor
import com.onresolve.jira.groovy.user.FieldBehaviours
import groovy.transform.BaseScript
import static com.atlassian.jira.issue.IssueFieldConstants.SUMMARY

@BaseScript FieldBehaviours fieldBehaviours
def currentUser = ComponentAccessor.getJiraAuthenticationContext().getUser()
def summary = getFieldById("summary")

summary.setFormValue("Education Request ${currentUser.name}")

It's necessary to change it so that instead of the current user it would put Specialists.

Using a post-function is acceptable but it would be better taking values from Specialists during filling in the Create issue form.
