JAVA API: How to get nested values of a custom field?

[Miraculous Ladybug]

Let's say I have a custom field called "Sponsors" which has the ID 12345. And the field has nested fields about cost centers. How do I access this field with the Java API com.atlassian.jira?

I access the sponsor field by 

issue.getCustomFieldValue(customFieldManager.getCustomFieldObject(12345L)

The json looks like this:

 "customfield_12345": {

"self": "https://jira.xxx",
"value": "Sponsor ABCD",
"id": "56789",
"disabled": false,
"child": {

"self": "https://jira.xx",
"value": "Cost Center ABCD",
"id": "42424",
"disabled": false

}
}

What kind of custom field are you using for Sponsor?

If I used something like Select List (cascading) as a custom nested field, the method you're using just returns the values in my custom field:

---

import com.atlassian.jira.component.ComponentAccessor

def issueManager = ComponentAccessor.getIssueManager()

def issue = issueManager.getIssueByCurrentKey("<issueKey>")

def customFieldManager = ComponentAccessor.getCustomFieldManager()

def customField = issue.getCustomFieldValue(customFieldManager.getCustomFieldObject(10403L))

return customField

Result: [null:Parent Option 1, 1:Child Option 2]
