Prevent creating sub-tasks if parent issue is closed/resolved

[Rajiv Ranjan]

How can I Prevent creating sub-tasks if the parent issue is closed/resolved?

I am aware that we can hide the sub-task from below two ways but I am looking for a script runner script to achieve this.

-  Hide the Create-Subtask UI element using one of the built-in Script Fragments. OR
-  We can add workflow transition, property jira.permission.edit=false

Since we don't want to hide the sub-task create button or disable edit issue, we have added a script validator to stop creating sub-task.

Validator on subtask create workflow.

issue.getParentObject().getStatus().name != "Done"

!("Done"==(issue.getParentObject().getStatus()))
(issue.getParentObject().getStatus().getName()=='Done')

Thanks for posting this Rajiv. 

Are you using a plug-in like Script Runner for this validator? Or can it be achieved without a plug-in?
