Is there a way to find all open issues with no sub-tasks, without using any external plugins like script runner? I've been trying to write a query for this and haven't had any luck. I've searched the web and run into the same answer (ie. Use a plugin like script runner).
Is that really the only way to find issues I'm looking for? If yes, does anyone know why standard Jira doesn't support the Sub-tasks field in advanced queries?
Thanks,
