Validate a value of a custom field based on state using script runner

[Nannette Mori]

Jira version 8.20.1

Script runner version6.56.0

I want to check on a value of a customfield and throw a message if the value is not valid and not allow transition to the next state.  i know I can put a validator on a transition but I do not want the user to be able to put a invalid value in that custom field in between state changes.  Is there a way to validate the value when transitioning to a certain state and not allow an invalid value between state changes using script runner

Would a behaviour help here?
On the edit of the field you do your checks and include the current state of the issue as well...

By using the setError() function you can also throw a custom error message on that specific field and it won't allow them to save the issue.

This is something we often use to validate input regardless of the state to be sure the value has a certain format (often with a regular expression attached)

The problem we are having is we can't get the current status of the issue.  We used what was in script runner documentation and script runner isn't recognizing the functions

This is from Script runner documentation

import com.atlassian.jira.component.ComponentAccessor

def workflow = ComponentAccessor.getWorkflowManager().getWorkflow(issue)

def wfd = workflow.getDescriptor()

def actionName = wfd.getAction(transientVars["actionId"] as int).getName() log.debug("Current action name: $actionName")

we were trying to use these functions in script runner behaviors

No, Jira does not have any hooks on the "edit" action that you could plumb a script into.

The closest you can get would be a listener that picks up edits, checks what the users have put into it and changes it to something valid if they've made a mistake.

You'll still need validotrs on the transitions as well.

The problem is we can't access the current state of the issue.  

How do we access the current state of the issue using Script runner

[Nic Brough -Adaptavist-]

In a scripted listener, you would extract the issue from the event, and then get the status from the issue.

def issue = event.issue

def status = issue.getStatus().getName()

Thank You for your assistance.

What is the syntax for the function below in a listener?

By using the setError() function you can also throw a custom error message on that specific field and it won't allow them to save the issue.

[Nannette Mori]

so using a listener won't work because we don't want to allow the user to save the issue.

Can you do this using behaviors?

[Nic Brough -Adaptavist-]

A listener can't stop an edit.  It is running after the edit is complete.

You could do something with Behaviours on the edit screen, yes.

The problem I am trying to solve is users are changing the Value of the Delivery Field to 6.x in between state transitions. Can you throw an invalid exception error in Behaviors?  How do you access the current state in Behaviors?
