Custom Field showing Last Modified User of an issue

[Brian Taylor]

I found some of code in the forum for a scripted field but can not get it to work with the latest software. 

Any help appreciated 

import com.atlassian.jira.component.ComponentAccessor

def changeHistoryManager = ComponentAccessor.getChangeHistoryManager()
def changeItems = changeHistoryManager.getAllChangeItems(issue)

if (changeItems?.size() > 0) {
    def userUtil = ComponentAccessor.getUserUtil()
    def userkey = changeItems.sort(false).last().getUserKey()
    userUtil.getUserByKey(userkey)
} else {
    null
}

scripted fields only fire on transitions.  and if you are okay with it being updated on transition then you dont even need SR to track.

Just add a custom field and add a "Update Issue Custom FIeld" post function with the field selected and this for the value: '%%CURRENT_USER%%'

Thanks for the feedback the best option would be a listener which I have not found any good examples as of yet

No, scripted fields are updated at a lot of other times.   It's an oversimplification, but you can almost always assume a scripted field is updated when the issue is indexed.  Transition, comment, edit, move, etc.

Nic - do you have any suggestions to the code listed as it does not appear to work 

[Nic Brough -Adaptavist-]

Apart from it not explicitly returning a value for the field to work with (as it's pseudo code, or code not intended for a field) what is it doing?

[Randy]

Ah that's good information Nic.  I didnt realize it also fired on comment/edit/move/index.  Thanks
