ScriptRunner Validator - Validate field from parent

[Ricardo_Gomes]

Hi,

I'm trying to add a workflow validator for a sub-task that must look at a field from the parent and only allow the transition if a certain value is selected from a custom single select list field.

In order to accomplish this I was trying to use ScriptRunner's Simple scripted validator by trying to get the value from the sub-task parent (which is a Task issue type) but I can't seem to make it work.

It would be easy for example, to know the status of the parent ticket by doing this:
issue.parentObject.statusObject.name == "Open"

I couldn't, however, find find a way to get the value of a custom field from the parent in order to validate that.

Please help.

Thank you!

It looks like the final answer was this format:

log.warn("Listener is fired");

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.watchers.WatcherManager
import com.atlassian.jira.user.util.UserManager
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.MutableIssue

def issue = event.issue as MutableIssue

//grabing some methods
WatcherManager watcherManager = ComponentAccessor.getWatcherManager()
UserManager userManager = ComponentAccessor.getUserManager()
CustomFieldManager customField = ComponentAccessor.getCustomFieldManager()

//Get the custom field value. .toString() is a must for the commentManager.create function, othervise it is throwing a validation error.
def cField1 = customField.getCustomFieldObjectByName("Customer")
def cFieldValue1 = issue.getCustomFieldValue(cField1).toString()

log.warn("Show the custom field value:" + cFieldValue1)

//Adding a watcher when this condition is met (NOTE: I used contains since my custom field was a multi-select)
if (cFieldValue1.contains("Something")) {

//Alternatively, you can use what was listed above: if (cFieldValue1 == "Something") {


def users = ["username"]
def watchUsers = {usernames ->;
usernames.each {
watcherManager.startWatching(userManager.getUserByName((String)it), issue)
}
}
watchUsers(users)

log.warn("true")
} else {
log.warn("false")
}

Hi Lubomir.

I think your postfunction is firing for sure. That is a static compilation error and I'm sure it's not what's making that postfunction fail. Could you add a 

log.debug "I'm in the postfunction" 

That way you can check the logs to make sure that it's actually getting executed.

Cheers!

Hi Daniel,

it is working now. I will put the solution here later today. Thank you for your effort so far.

Regarding the solution, I noticed that this definition was also marked by static type checking

def cFieldValue1 = issue.getCustomFieldValue(cField1).toString()

So a added a few lines:

import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.MutableIssue

and

def issue = event.issue as MutableIssue

and the code started to work as expected. So it seems that the issue declaration is not needed in post-function but in Scripted Listener is needed. I don't know why, but it did the job and after that the code was clear.
