Deny ability to change epic link on issue in certain status

[Jon]

Hi,

My issues have maybe 2 dozen fields and some are very critical and we would want them to not be able to be edited if the issue is in a certain status. epic link is one, which I am not sure if its handled differently that normal fields. I have looked at property keys but seems the only thing that could be done with that is to lock the entire issue which is not what we want either.

Hello,

Try to set the following property to the required status:

jira.permission.link.denied

[Jon]

Is it possible that only works for normal links and not epic links? 

What if I set a property on the epic instead that dictated what can be done on the issues linked to it?
