Hi there,
When transitioning a sub-task, which has required fields, from "draft" to "submit", validation of required fields does not work on pages other the "edit" screen.
It only works when I click on "edit" and hit "create." Then, I will get a list of required fields that need to be entered to continue.
How can extend this type of validation beyond the "edit" screen, so that when I transition a subtask, by hitting "submit" on the view screen, it checks to make sure all required custom fields are filled?

I am using JIRA v7.4.0 server. I've tried adding a workflow validator to check that a specific field has been set. Problem with that, we have several subtasks. And, the validator checks the specified field even though the selected subtask doesn't include that field.
Thank you very much for your time.
