Scripted field to list full names from multi user custom field

[Jeremy Coukoulis]

I am trying to create a scripted field which will populate with a list of users full names from a multi user picker field ("Award Nominees" customfied_21775)

I have tried the following script:

import com.atlassian.jira.component.ComponentAccessor

import com.atlassian.jira.issue.Issue

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

import com.atlassian.jira.user.ApplicationUser

 

CustomField multiuserCstFld = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("Award Nominees")

if (multiuserCstFld == null)

    return "custom field not found"

 

StringBuilder result = new StringBuilder();

 

for(ApplicationUser user: (ArrayList) multiuserCstFld.getValue(issue))

    result.append(user.getName() + "/")

 

return result.toString().substring(0, result.toString().length() - 1)

but I get the following syntax error:

[Static type checking] - Cannot loop with element of type com.atlassian.jira.user.ApplicationUser with collection of type java.util.ArrayList

I'm at a loss as to what is wrong.  I am on JIRA version 7.1.9 and using scriptrunner version 4.3.13

Any help would be greatly appreciated.  Thank you!

If you want their full names, you'll want to use the getDisplayName method. 

import com.atlassian.jira.component.ComponentAccessor
def awardNomineesField = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("Award Nominees")
if (!awardNomineesField) { return null }
issue.getCustomFieldValue(awardNomineesField)?.collect{ 
    it.displayName 
}?.join(" / ")

You are correct.  I did need to change getname to getDisplayName to show the full name.  Thank you.

Try this code

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.user.ApplicationUser

CustomField multiuserCstFld = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("Award Nominees")

if (multiuserCstFld == null)
    return "custom field not found"

StringBuilder result = new StringBuilder();

for(ApplicationUser user: (ArrayList<ApplicationUser>) multiuserCstFld.getValue(issue))
    result.append(user.getName() + "/")

return result.toString().substring(0, result.toString().length() - 1)

That was it.  I was missing the <ApplicationUser> after the ArrayList. No more error! Thank you very much!
