checking a checkbox field of a parrent issue in a post function of an epic

[andres jerez]

Hi, im trying to update a checkbox custom field that only has a value ("Lost") on a parent issues right after i update one of the epics to a particular status in our kanban board, but no matter which configuration of the "Set field value post-function" in the JMWE i use, it still never changes, in the value field i was trying something like {{targetIssue.fields["Lost"] | join("," , "Lost")}},  but no changes, i tried, also just to let the value field like "Lost" but also didnt work. what could i be doing here wrong?

As a target issue i have: issues that belong to the current issue Epic.

Field: Lost

Value: (i tried multiples as mentioned)

Please use this as a reference.

CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager()
CustomField approvalNeeded = customFieldManager.getCustomFieldObjectByName("Approval Needed")
 
String value = (String) issue.getCustomFieldValue(approvalNeeded)

Now, the value of Approval needed into the variable 'value' and go ahead with further coding as you required.

Here's the same script, with imports and more relaxed typing:

import com.atlassian.jira.component.ComponentAccessor

def customFieldManager = ComponentAccessor.getCustomFieldManager()
def approvalNeeded = customFieldManager.getCustomFieldObjectByName("Approval Needed")
def value = issue.getCustomFieldValue(approvalNeeded)

See also the examples using the OptionsManager to show you how to get the list of possible values for your select list field. https://scriptrunner.adaptavist.com/4.3.7/jira/recipes/behaviours/select-list-other.html. You probably won't need them for your use case, but you may for similar work.
