How to default Subtasks to same values that the parent has?

[Dmitry Tyomkin]

To ScriptRunner/Behaviors gurus out there. I've tried to use the suggested script at https://scriptrunner.adaptavist.com/latest/jira/recipes/behaviours/subtask-default-fields.html for Subtask defaulting. However, the script is not compiling, the groovy interpreter complaining on static type checking problem for these code snippets: "parentValue[0] instanceof Option" and "parentValue*.optionId". It appears that Jira/SR have changed something over last year or so and no longer support default type casting from Object to List. Would you know what needs to be done to make this code legit again or propose an alternative to default subtask values on Create screen?

Your running into static type checking errors due to limitations listed here, where the custom field value is not explcitly typed. Although the script would have worked when run.

You don't have to worry about the deprecations but to fix the other static type checking errors you can use:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.customfields.option.Option
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.web.util.OutlookDate
import com.atlassian.jira.web.util.OutlookDateManager
import com.onresolve.jira.groovy.user.FieldBehaviours
import com.onresolve.jira.groovy.user.FormField
import groovy.transform.BaseScript

import java.sql.Timestamp

import static com.atlassian.jira.issue.IssueFieldConstants.*

@BaseScript FieldBehaviours fieldBehaviours

FormField field = getFieldById(getFieldChanged())
FormField parent = getFieldById("parentIssueId")
Long parentIssueId = parent.getFormValue() as Long

if (!parentIssueId || field.getFormValue()) {
    // this is not a subtask, or the field already has data
    return
}

def issueManager = ComponentAccessor.getIssueManager()
def parentIssue = issueManager.getIssueObject(parentIssueId)
def customFieldManager = ComponentAccessor.getCustomFieldManager()

// REMOVE OR MODIFY THE SETTING OF THESE FIELDS AS NECESSARY
getFieldById(SUMMARY).setFormValue(parentIssue.summary)
getFieldById(PRIORITY).setFormValue(parentIssue.getPriorityObject().id)

OutlookDate outlookDate = ComponentAccessor.getComponent(OutlookDateManager).getOutlookDate(Locale.getDefault())
getFieldById(DUE_DATE).setFormValue(outlookDate.formatDMY(parentIssue.getDueDate()))

getFieldById(COMPONENTS).setFormValue(parentIssue.componentObjects*.id)
getFieldById(AFFECTED_VERSIONS).setFormValue(parentIssue.affectedVersions*.id)
getFieldById(FIX_FOR_VERSIONS).setFormValue(parentIssue.fixVersions*.id)
getFieldById(ASSIGNEE).setFormValue(parentIssue.assigneeId)
getFieldById(ENVIRONMENT).setFormValue(parentIssue.environment)
getFieldById(DESCRIPTION).setFormValue(parentIssue.description)
getFieldById(SECURITY).setFormValue(parentIssue.securityLevelId)
getFieldById(LABELS).setFormValue(parentIssue.labels)

// IF YOU DON'T WANT CUSTOM FIELDS COPIED REMOVE EVERYTHING BELOW HERE
// IF YOU ONLY WANT SOME FIELDS INHERITED ADD THEM TO THE LIST BELOW, OR LEAVE EMPTY FOR ALL
// eg ['Name of first custom field', 'Name of second custom field']
List copyCustomFields = []

List<CustomField> parentFields = customFieldManager.getCustomFieldObjects(parentIssue)
parentFields.each { CustomField cf ->
    if (copyCustomFields && !copyCustomFields.contains(cf.name)) {
        return
    }

    def parentValue = cf.getValue(parentIssue) as List<Option>

    if (!parentValue) {
        return
    }

    getFieldById(cf.id).setFormValue(parentValue)
    log.debug("parentValue: ${parentValue?.class} for type ${cf.name}")

    if (parentValue instanceof Timestamp) {
        getFieldById(cf.id).setFormValue(outlookDate.formatDMY(parentValue))
    } else if (parentValue instanceof Option) {
        getFieldById(cf.id).setFormValue(parentValue.optionId)
    } else if (parentValue instanceof List && parentValue[0] instanceof Option) {
        getFieldById(cf.id).setFormValue(parentValue*.optionId)
    } else {
        getFieldById(cf.id).setFormValue(parentValue)
    }
}

We'll update the documentation so it's more clear.

Hope this helps.
