That’s an interesting answer, since I thought that required fields in workflow is an important part of a JIRA project. We can’t just abandon them to use Exalate, because it will cause inconsistency within the issues. There must be some ways to provide these.
Unfortunately, this isn’t possible on Jira Server, you would have to remove the requirement or use a different transition. I’m going to open a development ticket so this feature can be integrated to the product in the future.
