What is the best way to make issue Assignee field read-only in particular workflow states?

[Alexnder Kolinchenko]

We need to make Assignee field read-only when there are particular workflow stages (not transitions).

We have tried making it via Behaviors but there is a button on the screen "Assign to me" that stays active (and works) while read-only status of the field set in Behaviors section. How can we disable this button as well?

I tried removing Assignee field from Edit screen but it works only for transitions (as we can make separate Edit screen for transitions only as I understand).

May be there is a better way to do such a trick?

Try to put into the status properties the following property

jira.permission.assign.denied
