Remove "Assign to Me" under the assignee on view screen

Question

Case:

Controlling assignment via workflow for certain workflows.

I am familiar with the JS banner hack to remove this function and we used it for years, but have since started heavily investing in behaviours and it was causing issues so I've removed the banner script.

Script fragments doesn't seem to have the option to remove this.
I've disabled the assign-to-me module and it's still present.

We are on Server 8.5.

Specifically I am wanting to remove:

Regards,
Steven

Dear @Steven Mustari ,

there is a work-a-round described in the referring suggestion: https://jira.atlassian.com/browse/JRASERVER-38117

Have you tried this?

So long

HI @Steven Mustari

If your announcement banner javascript is interfering with Behaviors, I'd fix the interference before throwing the baby out with the bathwater. Maybe you had other too complex scripts that were interfering.

In this article (linked from the issue linked by @Thomas Deiler), the css should be fairly limited in scope. I can't imagine how that would interfere with behaviors.

If you are against putting content like that in the banner script specifically, you could use scriptrunner fragment to "Install a web resource". For this, you would still write either javascript or css and store it in a file and point to that file from the fragment. This code/file will now be present in every page (based on the selected context), just like the banner.

Of course, the other option is to control this via your permission scheme. Remove that permission from most users and only change the assignee via the workflow. I don't recall off the top of my head if using built-in post functions respect the permission and would fail the transition.. but if it does, then use a scripted post function and impersonate an admin account for the duration of that function. 
Now... that' getting pretty complex... but if you need to have some people able to manually assign some of the time, you would need to start managing the assignee in a custom field and copy the value to the assignee field using transitions.

All told... I think the css/javascript option is better, just keep it very narrow and specific. You could even make it conditional if you need to by using a custom web-panel that conditionally output a meta tag like <mata name="hide-assign-me" content="true"/> and have your javascript look for that value when deciding to act or not.

Hi Steven

I know you just said you are familiar with the js-injection, but maybe its worth looking into this answer I posted for someone else.

https://community.atlassian.com/t5/Jira-questions/How-to-disable-Assign-to-me-functionality-for-a-few-specific/qaq-p/1240842

The solution uses a scriptrunner web panel and css-injection via js to hide the link.
As there are conditions and locations you can set in web panels (to narrow down when and where it is executed), it might be interesting for you.
