Sum of custom field values from subtasks in parent issue custom by listener

[Kim Chen]

Hello guys,

I wanted to use scriptrunner listener to  sum custom field values of all subtask for parent issue type .

my code is :

def currentIssue = issue

if (currentIssue.parentObject.issueTypeObject.name == 'Task') {

def changeHistoryManager = ComponentAccessor.changeHistoryManager

def lastChangeItem = changeHistoryManager.getAllChangeItems(currentIssue).last()

if (lastChangeItem?.field == '10409') {

def totalWeakness = 0

Issues.search("project = '${currentIssue.projectObject.key}' AND parent ='${currentIssue.parentObject.key}' AND issuetype = 'Sub-task'").each { subtask ->

def weaknessValue = subtask.getCustomFieldValue('10409') as Double

if (weaknessValue) {

totalWeakness += weaknessValue

}

}

def parentIssue = currentIssue.parentObject

parentIssue.update {

setCustomFieldValue(10410, totalWeakness.toString())

}

}

}

now when I update the issue , code can run,10410 value will become  all Sub-task 10409 sum value,

but when I create a new Sub-task from task , the value of 10410 has not change, can someone helps me~

and this is my listener setting:
