Values in two user picker Custom fields should be copy to a multi user picker custom field

[Satyanarayana Singamsetti]

Hi ,

I need the code for Copy the value of two user-pickers custom field values into another custom field which is a multi user picker.

ex: CF1: user1, CF2: user2 and for CF3 the value should be as "user1,user2". CF3 is a User Picker (multiple users).

Note: CF3 will be empty during creation of issue. during the flow of issue once CF1 and CF2 gets values by the code CF3 should populate the merged value.

I tried with this below code but not worked :(

package UpdateIssue
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.event.type.EventDispatchOption
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.IssueManager
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder
import com.atlassian.jira.issue.UpdateIssueRequest
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.project.Project
import com.atlassian.jira.user.ApplicationUser
import com.atlassian.jira.issue.ModifiedValue

IssueManager issueManager = ComponentAccessor.getIssueManager();
MutableIssue issue = issueManager.getIssueObject("TKT-16")
if (issue)
{
CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager();

CustomField cstFld1 = customFieldManager.getCustomFieldObject("Customfield_1123")
CustomField cstFld2 = customFieldManager.getCustomFieldObject("Customfield_1123")
CustomField cstFld3 = customFieldManager.getCustomFieldObject("Customfield_1144")

ApplicationUser curUser = ComponentAccessor.getJiraAuthenticationContext().getUser();
UpdateIssueRequest updateIssueRequest = new UpdateIssueRequest(new UpdateIssueRequest.UpdateIssueRequestBuilder().eventDispatchOption(EventDispatchOption.ISSUE_UPDATED).sendMail(false))

// issue.setCustomFieldObject(cstFld1.getValue(issue).toString() + "," + cstFld2.getValue(issue).toString())
def CR = (cstFld1.getValue(issue).toString() + "," + cstFld2.getValue(issue).toString())
def changeHolder = new DefaultIssueChangeHolder()
cstFld3.updateValue(null, issue, new ModifiedValue(cstFld3,CR),changeHolder)
}

Getting this error

I know why i get this error because

cstFld3 is Customfield with user picker and  CR is a string value, but don't know how to make string to custom field value(user picker).

Could some one help me on it.

Thanks in advance

Thanks @Sreenivasaraju P , used your idea with different approach

}
log.info(userList.unique())
}else{
if(crV1 != null && crV2 != null){
userList.addAll([crV1,crV2])
log.info(userList.unique())
}
}
if(codeReviewers != null && userList != null){
//issue.setCustomFieldValue(codeReviewers, userList.unique() )
//issueManager.updateIssue(user, issue, EventDispatchOption.ISSUE_ASSIGNED, false)
codeReviewers.updateValue(null, issue, new ModifiedValue(issue.getCustomFieldValue(codeReviewers), userList.unique()),changeHolder)
}
}

Its working fine :)

Hi @Satyanarayana Singamsetti ,

You can do other way around.  

1. Get the application users from your source fields (from single user picker fields in your case cstFld1 , cstFld2)
   ApplicationUser userValue1 = (ApplicationUser)mIssue.getCustomFieldValue(cstFld1 );
   ApplicationUser userValue2 = (ApplicationUser)mIssue.getCustomFieldValue(cstFld2 );
2.  Get the collection of application users from destination field (in your case cstFld3). 
   Collection<ApplicationUser> usersList = (Collection<ApplicationUser>)mIssue.getCustomFieldValue(cstFld3 );
3. Add the application users to the userlist.
   usersList.add(userValue1 );
   usersList.add(userValue2 );
4. set the custom field value of the with the user list.
   mIssue.setCustomFieldValue(cstFld3,usersList);

I hope this may help you.

Thanks for the reply @Sreenivasaraju P 

I tried but getting this error

Script console script failed: java.lang.NullPointerException

and multi-user field didn't updated with users

Got the code.
