Validator-Based Post Function

Introduction

This post function allows you to execute any post function when a validator is met. The validator may come from transition validators or you can use any other validator available in Jira.

It can be used for, e.g.:

• Updating an issue field if another field has been updated on the transition screen.
• Assigning an issue to a lead developer if the current user has some project permissions.

There is a similar post function that uses conditions instead of validators. It can be very useful. Please check Condition Based Post Function.

Post function parameters

 Post function takes following parameters:

• Validator - a validator to be checked.
  
• Inverse validator - allows to run a post function when a validator is not met.
  
• Post function - a post function to be executed.

Please note that validators and post functions may require some extra parameters.
