Show all other sub-tasks in sub-tasks based on parent

[Oleksiy Ohmush]

Is it possible to use issue.function in same function? like

issueFunction in subtasksOf("r issueFunction in parentsOf("currentissue()")") ?

I try to show in Sub-task all other sub-task from same parent

Hi,

Are we talking about JQL only ? This request has been working fine with me : 

issueFunction in subtasksOf("issueFunction in parentsOf('key=ABC-123')")
