ScriptRunner Cloud get issue parent

[Robert Achmann]

I understand that, in a Workflow scriptrunner post function, the issue object is available.

Can someone point me to the location of the documentation that lists all of the issue members and how to access them? (ie how to set a custom date field).

Specifically, I need to know :

• how to find a sub-task's parent id
• how to access a specific custom field in the subtask
• how to get and update a custom field in the parent.

For example, to findd a custom field value, I see two approaches:

def customFieldId = fields.find { it.name == 'Flight End' }.id as String 
def customFieldValue = (issue.fields[customFieldId] as Map)?.value

and

def inputFlightEndId = customFields.find { it.name == 'Flight End' }?.id
def input1 = issue.fields[inputFlightEndId]

Which is correct?

Thanks!
