Features used to implement the example

• Boolean condition and validator with math. date-time or text-string terms

Example: Block transition until all sub-tasks are in a specific status category

In this example, moving the current issue to status "Done" should only be possible when all sub-tasks are in status category "Done" - otherwise the transition button should be hidden.

For this, a Boolean condition and validator with math. date-time or text-string terms is needed for on the transition to "Done" on the current issue (the parent).

The configuration will look like this:

Boolean expression to be evaluated is: count(filterByPredicate(subtasks(), ^%{00144} != "Done")) = 0  

Note that:

• %{00144} is field code for field "Issue status category"

After adding the condition, . the issue cannot be transitioned as long as there are sub-tasks that are not yet in status category "Done":

As soon as all sub-tasks are in status category "Done", the parent issue can be transitioned as well:
