Introduction

Use the table grid editor to create a list of subtasks


This is a more advanced example how you can create a list of subtasks based on the information collected in the grid.

Then by transitioning the 'Create Subtasks'  workflow action, all rows in the action grid with status 'Open' will be transformed into a subtask.

Solution

Setting up the script

Some assumptions

  • You did setup a standard action grid (like the one which is set by default)
  • You have configured a subtask issuetype 'action'
  • You installed the Script Runner
  • You configured a workflow transition - 'Create subtasks' with a post function 'Script postfunction' pointing to a groovy script on the filesystem

After the Java API was released in v 1.18.0 you can use it to avoid direct connection to the database.
