Changes not saved when transition validation is false

Question

I have create a validation script in one transition.
I added a customfield update in the validation, so is something like this

if validation == true

{ MutableIssue mi = (MutableIssue) issue; mi.setCustomFieldValue(CampoAPPT, "En Progreso"); ComponentAccessor.getIssueManager().updateIssue(currentUser, mi, EventDispatchOption.ISSUE_UPDATED, false); return true }

else

{ MutableIssue mi = (MutableIssue) issue; mi.setCustomFieldValue(CampoAPPT, "No Agendado"); ComponentAccessor.getIssueManager().updateIssue(currentUser, mi, EventDispatchOption.ISSUE_UPDATED, false); return false }

If i execute this in the console, i get the customfield updated in both cases. But if i do the transition, false validation doesn't update the field

The update can't run, you have not got to the point where you can write anything to the issue in a validator.

You will need to validate first, returning a pass or fail, and then do the update in a post function.

The reason why i'm using a Validator is that my script calls a REST API on another platform.

If the call goes OK, i do the transition.

But if the call fails, i would like to update a customfield and add a comment.

As far as i can see, when validation fails, the update doesn't run.

Is there a way to force the issue (mutable issue) to be saved?

Validators should not update fields.  A validator is for checking input, and the only thing they do is return a pass or a fail (with an error message, optionally)

Do not try to do this.  Move the custom field update into a post function, after you know the person has entered something that is valid.
