When you add this validator to a transition and trigger the transition, the add-on checks the result of the Jira expression. If it returns true the validation will pass. If it returns false or any non-boolean value, a validation error message is displayed.
Use case
A typical use of this workflow validator is to validate that the field of the issue has a specific value or the current user belongs to a specific group during the transition. Consider a use case where you want to block the user from triggering the “Approve” transition when the current user is not in the “Approvers” field. To configure this:
Add the “Build-your-own (scripted) validator” to the “Approve” transition
Input the following code under “Jira Expression”
Code Block !! issue.customfield_10002 && issue.customfield_10002.some(it => it == user)
Another use of this validator is to validate the comment added during the transition. Jira expressions do not facilitate a context variable to get the comment added during the transition. But you can access the comment on the transition screen with a workaround. Consider a use case where you want to block the user from rejecting the “Bug” without a comment with atleast 10 characters. To configure this:
Add the “Build-your-own (scripted) validator” to the “Approve” transition
Input the following code under “Jira Expression”
Code Block issue.comments.some(comment => !comment.id && comment.body.plainText.length > 10)
This basically tests whether there is a comment that has no ID (and therefore is new) and whose body length is > 10.
