There are quite a few examples showing how to do this by linking a task to an epic, but I want the task added to the epic.
Step 1:
A user creates an Epic. The epic has a custom field titled Brand:
Step 2:
When the Epic is saved, with a Brand selection it triggers a rule.
Step 3:
The rule, based upon issue type = Epic, and Field Brand = [Some Value] Create one or many tasks.
This works like a champ, I can create in some instances up to 35 tasks if all the options are selected.
Step 4
What I can't get working is showing these tasks as part of the Epic in the backlog of my Kanban board.
(Slimmed down version of my rule)
*Note
I can get this to relate to the Epic fine.
However, that doesn't help to have a bunch of tasks related to an epic.
My first iteration was a custom issue with sub tasks. The sub tasks worked fine, so I guess they automatically relate to the parent issue. My users decided they wanted to keep the Epic - Task relationship instead.
