updating the watcher field using scriptrunner

[sahere]

hi all

in the create issue screen there is a field as Watchers, I want to update this field even if the user didn't do it in the creating step. I used following script in scriptrunner post function so that add "b-atb" user to Watcher list :

import com.atlassian.jira.issue.MutableIssue

import com.atlassian.jira.component.ComponentAccessor;

import com.atlassian.jira.ComponentManager;

import com.atlassian.jira.issue.CustomFieldManager;

import com.atlassian.jira.issue.fields.CustomField;

import com.atlassian.jira.issue.IssueManager;

import com.atlassian.jira.issue.Issue

import com.atlassian.jira.issue.CustomFieldManager

import com.atlassian.jira.issue.MutableIssue

def customFieldManager = ComponentAccessor.getCustomFieldManager()

MutableIssue issue = issue as MutableIssue

def myField = customFieldManager.getCustomFieldObjectByName("Watchers")

issue.setCustomFieldValue(myField,'b-atb')

but after publishing, when i tried to create an issue, following message has been shown in the create screen:

We can't create this issue for you right now, it could be due to unsupported content you've entered into one or more of the issue fields. If this situation persists, contact your administrator as they'll be able to access more specific information in the log file.

any advise will be so appreciated

Hi @sahere ,

I suppose You need use startWatching(ApplicationUser user, Issue issue)

Also not sure setCustomFieldValue(myField,'b-atb') it not work because You try set String to Watch field.

To find user You can use DefaultUserManager.

Hello @sahere 

You are getting the error, because you are treating "watcher" as a custom field and thus gettting error in your logs.

Please use watcher Manager as defined in API

https://docs.atlassian.com/software/jira/docs/api/7.6.1/com/atlassian/jira/issue/watchers/WatcherManager.html

Example code here, please see answer from Henning Tietgens
