I tried to establish two mandatory fields for an issue.
I used the workflow jetbrains-youtrack-mandatoryField and added a rule "Don't allow to submit issue without Assignee" which is pretty much the same as the rule "Don't allow to submit issue without Due Date set" I only exchanged "Due Date" with "Assignee" and changed the message.
The rule works find BUT both rules do not work at the same time. When I create a new issue I get the message "You must set the due date". If I try to set the due date, I get the other message "Please assign issue" and vice versa.
It is not possible to set the required fields. Alone every rule works fine.
A bug? Or do I have to set up this in another way?
