Update issue manually vs script

[Neta Elyakim]

Hey everyone,

I'm developing a process in Jira and I need help understanding the difference between update the issue manually (click on edit > update) and update issue by script https://docs.atlassian.com/software/jira/docs/api/7.6.1/com/atlassian/jira/issue/IssueManager.html#updateIssue-com.atlassian.jira.user.ApplicationUser-com.atlassian.jira.issue.MutableIssue-com.atlassian.jira.event.type.EventDispatchOption-boolean-\\ 

I have a field that updates if I update the issue manually but not in a script.
I'm using "Power Database Fields PRO" add-on that gets the value from the DB (this part is working) the problem is just with the update issue (manually vs script).
For scripting, I'm using ScriptRunner.

I hope someone can help me understand if I can add something to my script in order to imitate the behavior of the manual action.

Thanks

there should be no real difference.  When you click edit > update, it's just a different way of calling the same functions that a script calls.

My best guess is that the app you're using (power database fields pro) is doing something on the front-end with the UI, as well as updating on the back-end.  Scripts do not go through the front-end, so anything injected there won't happen, and if you need them to, you'll have to replicate the function in the script.
