Make Multi-Level Cascading Select field required at multiple levels

Tested on September 27, 2024, Jira 9.12.8, ScriptRunner 8.33.0, Multi-Level Cascading Select 7.0.2.

There is no limit to the depth of a Multi-Level Cascading Select field context. There are scenarios where a number of levels need to be selected by the user when creating an issue, but this cannot be done by using the regular “Required“ Jira option for issue fields.

To solve this, we have made a script that allows you to decide exactly how many levels are required to be populated by the user.

These are the steps to follow to replicate this behaviour:

In the ScriptRunner tab, navigate to Behaviours.
Create a new Behaviour and relative mapping.
At the bottom of the page, add your Multi Level Cascading Select field by clicking on “Add Field”.
Once the field is added, click on Create Script and paste the following script:

import groovy.json.JsonSlurper;

// Variables
def mlcsField = 'Multi-Level Cascading Select field'; //Enter the name of your MLCS field.
def levels = 2; //The levels you require to be populated.

def mlcs = getFieldByName(mlcsField);
String fieldValue = mlcs.getFormValue();
if(!fieldValue.isEmpty()) {
    List json = (List) new JsonSlurper().parseText(fieldValue);
    // Imposto o rimuovo l'errore basato sulla dimensione dell'ArrayList
    mlcs.setError(json.size() < levels ? "PLEASE NOTE: At least $levels drop-downs are required for $mlcsField" : null);
}else{
    mlcs.setError("Required field " + mlcsField);
}

You can now open any Create/Edit issue screen to test the new Behaviour.
