I am trying to use the default JIRA conditions so that a story cannot be transitioned to 'in progress' unless *at least one* task is in progress. however i have the impression the default condition "All sub-tasks must have one of the following statuses to allow parent issue transitions" means that *all* tasks must meet that criteria, which is stupid, as you will never have all tasks in the same status, and you do not want for example to artificially drag all your tasks to 'in progress' when you're only working on one.
am i misunderstanding something? thanks
