Condition to hide "Created Linked issue"

[zaharovvv_suek_ru]

I have a condition to hide "Created Linked issue" if issue is:
- project of key is "LO"
- type of issue is "Epic"
- status of issue is "Closed"

So I write the following query:

jiraHelper.project?.key != "LO" &&
 issue?.issueType?.name != 'Epic' &&
 issue?.getStatus()?.getName() != 'Closed'

and the above query hides "Created Linked issue" in issue types such as "New Feature", "Epic":

I've tried to change the query:

jiraHelper.project?.key == "LO" &&
 issue?.issueType?.name == 'Epic' &&
 issue?.getStatus()?.getName() != 'Closed'

However, it again hides "Created Linked issue" in issue types such as "New Feature", "Epic".

How can I hide "Created Linked issue" if issue is:
- project of key is "LO"
- type of issue is "Epic"
- status of issue is "Closed"
?

Hello @zaharovvv_suek_ru

!(jiraHelper.project?.key == "LO" &&
 issue?.issueType?.name == 'Epic' &&
 issue?.getStatus()?.getName() == 'Closed')

Above code means *NOT* of

- project of key is "LO"
- type of issue is "Epic"
- status of issue is "Closed"

You can put this in the condition in the web fragment

If you want to limit the link issue function just for one status in one workflow- a better solution will be to put on the status properties :

jira.permission.link.denied

It's work.

You can just go to you relevant workflow-> open as a diagram -> click on the status -> click Properties -> then add "jira.permission.link.denied" under Property Key -> add -> publish workflow.
