Auto add subtask assignees as watchers of parent issue?

When we create a subtask for any issue, we would like to automatically add the assignee of that subtask as a watcher on the parent issue. We have ScriptRunner, JJUPIN, etc installed but I can't find a specific post-function script for what we want.

Hi Moriah,

Try adding the following SIL script post-function on the create issue transition:

if(isNotNull(parent)) {

%parent%.watchers = addElementIfNotExist(%parent%.watchers, assignee);


Make sure that you put the SIL post-function last in the list of post-fuctions for the create issue transition, after the issue is created.

Kind Regards,



Did the provided SIL script helped you?

Sorry, I haven't had a chance to try it yet. I am knee deep in transitioning a team but will definitely try this out over the weekend. Thank you for the quick response!

Hi Moriah,

If the SIL script worked for you, please consider marking the answer as accepted.



Sorry it took so long to try it. I actually couldn't get it to work. I copied your exact script, added it to the workflow and placed it last in the list of post-functions. (I also tried it in different positions on that list too.) The post function list includes:

Creates the issue originally.

Fire a Issue Created event that can be processed by the listeners.
Assign the issue to the lead developer.
This will run the Add sub assignees as parent watchers SIL program
The file of your program is stored as: /var/atlassian/application-data/jira/silprograms/Addsubassigneesasparentwatchers_1.sil
Start your programs with code comments, this way it will show here (max 3 lines)

Did you publish the workflow after adding the SIL post-function?

Is there any error in the log when creating a sub-task?

Argh. I was making changes to a workflow that was not associated with the project. Sorry, it DOES work :)

Thank you for your patience!

Yes, I published it. There were no log errors.

There is no post-function to be found for such a specific action.

You have to write your own post-function as a "groovy" or "java plugin" [1].

best regards,


1 : since you are already using scriptrunner, i would go with a groovy script.
