how to get user full name who ever transitioned the jira issue

[Ramaiah Pendli]

Hi,

we are using below script to get the Rejecter user id when the issue moved to Rejected state but we require the full name in custom filed. plz some one help me to get the user full from the statement bolck "def userid = changeItems.collect { userUtil.getUserByKey(it.userKey).name}" 

import com.atlassian.jira.component.ComponentAccessor;

def historyManager = ComponentAccessor.getChangeHistoryManager()
def userUtil = ComponentAccessor.getUserUtil()

def changeItems = historyManager.getAllChangeItems(issue).findAll { changeItem ->
changeItem.field == "status" && changeItem.toValues.find{ it.value == "Rejected"} && !(changeItem.fromValues.find{ it.value == "Rejected"})
}

def userid = changeItems.collect { userUtil.getUserByKey(it.userKey).name}
if(userid)
userid.last()

Perhaps this would work for you: 

def userid = changeItems.collect { userUtil.getUserByKey(it.userKey).getDisplayName()}
