Validators are used to validate the input made on the transition screen after the transition is triggered.
Jira Misc Workflow Extensions makes the following Validators available to Jira administrators:
- Build-your-own (scripted) Validator — A workflow validator that is based on the result of a Jira expression.
- Comment Required Validator — A workflow validator that forces users to enter a comment during a transition. If the user does not enter a comment, a custom error message will be displayed.
- Field Required Validator — A workflow validator which ensures that the specified field has a value during a transition.
- Linked Issues Validator — A workflow validator that ensures the issues linked to the current issue (existing and ones added during the transition) have certain characteristics. The transition to which the validator is added will pass only when the linked issues respect these characteristics.
- Linked Issues Status Validator — A workflow validator which ensures that the current issue's linked issues (existing and ones added during the transition) respect the specified condition against selected statuses.
