Add a list of watchers during CREATE Post-Function

[Martin Hohenberg]

I am trying to add users as watchers during the CREATE post-function with a scriptrunner script. The following code (starting at line 236)

    def usernames = ["user1", "user2", "user3"];
    usernames.each {
        def user = ComponentAccessor.getUserManager().getUserByName("${it}")   
        if (user != null) ComponentAccessor.getWatcherManager().startWatching(user, issue) 
    }

results in the following error message:

2018-09-11 17:26:13,177 ERROR [workflow.ScriptWorkflowFunction]: Script function failed on issue: null, actionId: 1, file: <inline script>
java.lang.NullPointerException

	at Script203$_run_closure1.doCall(Script203.groovy:239)
	at Script203.run(Script203.groovy:237

I *guess* that the issue arises because the *issue* is in the process of being created and does not have all the necessary information stored at this point in time in the issue object.

Solutions from two years ago mention the deprecated method issue.getGenericValue(), but that approach seems to no longer work with WatcherManager.startWatching().

What is the preferred way of doing this?

Hi Martin,

probably you need to move your pf order. You need to move this script after "Creates the issue originally.". It should solve your issue.

This solved the problem. Thank you :)

Hi Martin,

try using this code :

import com.atlassian.jira.component.ComponentAccessor;

import com.atlassian.jira.issue.watchers.WatcherManager;

import com.atlassian.jira.user.ApplicationUser;
import com.atlassian.jira.user.util.UserManager;

String[] users = {"user1", "user2", "user3"};
UserManager userManager = ComponentAccessor.getUserManager();
WatcherManager watcherManager = ComponentAccessor.getWatcherManager();
for(String us : users){
 ApplicationUser user = userManager.getUserByKey(us);
 if(user!=null)
   watcherManager.startWatching(user, issue);
}

 Hope this helps,

Ciao,

Fabio

Hi Fabio,

thank you for your suggestion. Unfortunately, that does not solve my situation:

2018-09-12 09:45:18,964 ERROR [workflow.ScriptWorkflowFunction]: Script function failed on issue: null, actionId: 1, file: <inline script>

I guess the problem still lies with the issue. Is the problem related to how I define that? Line 245 is this one:

watcherManager.startWatching(user, issue);

Way up the script, there is the following line:

MutableIssue issue = issue;
