I am looking for a way to only show Tasks where all Sub-Tasks do not (!=) have status Open.
I can select Tasks by using:
issuetype = Task
But how can I access the Sub-Tasks of these Tasks?
Seems like you are trying to find stale tasks that should be closed off because all of the sub-tasks are complete?
The only way to do this AFAIK is with an addon like Scriprunner where you can use "issuefunction" parameter. there are other threads in the Community that illustrate how this can be done.
