Post Function Create Sub-Task Script not working on issue creation

[Aaron Blaquiere]

JIRA 5.1.2 we are trying to create a linked sub-task on issue creation. It is creating the sub-task, but not linking it to the parent ticket.

Post Function Order:

Create Issue

Script Workflow Function: Create a subtask

Re-Index

Raise Issue Created Event

Create Sub-Task Settings:

Condition: Blank

Target Issue Type: Appropriate Issue Type

Subtask Summary: Data-Injest/Enrich

Additional issue actions: issue.summary = 'Ingest/Enrich: ' + issue.summary
def cf = customFieldManager.getCustomFieldObjects(issue).find {it.name == 'GB'}
issue.setCustomFieldValue(cf, '')

Subtask Action: Blank

The upgrade to 5.1.2 affected impacted the custom field data model. Instead of:

issue.setCustomFieldValue(cf, '')

use

issue.setCustomFieldValue(cf, null)
