How to set username to a user picker cf?

[Jeffrey Melies]

I'm new to groovy and to the Script Runner. 

We are using Script Runner 5.2.1 and JIRA Server 7.5.1

In a post function I'm trying to populate 2 User Picker cf's with the component lead and component watchers.  I have figured out how to query the db and return both userID for the lead and watcher, now I need to populate them in the user picker fields and for the life of me I can't figure out how to do it, any help would be greatly appreciated.

This is what I have so far.

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.MutableIssue

//Just for testing the script I'm pulling in a specific issue, when I add this as a post function, I'll modify this line by adding issue
MutableIssue issue = "cc-9396"

MutableIssue SubjectIssue = issue
def customFieldManager = ComponentAccessor.getCustomFieldManager()
def validateUserCN = SubjectIssue.getCustomFieldValue(customFieldManager.getCustomFieldObjectByName("Business Reviewer"))

SubjectIssue.setCustomFieldValue(validateUserCN, "t16384");

Don't have the methods handy, but if you're still looking. you dont need the db for this, component lead and watchers you can grab from the api - they will also return ApplicationUser objects.

To set the field value, you'll need to actually update the field. Top of my head, i think it was something like ModifiedFieldValue...

Maybe that gets you looking in the right direction (if you're still looking ;)  )

Cheers

Can anyone help answer this, I would think it's pretty straight forward.
