How to only show one transition based on sub-tasks status? Jira software cloud

Jesper Fransson_e2llz4

I have a workflow with two transitions going from In Review -> Closed. We can call them Transition 1 and Transition 2.

Only one of these transitions should be available at all times.

The condition logic should be as follow:
When you transition a parent issue with multiple sub-task which are ALL closed - Transition 1 should only be available. This is doable and works with the native built in condition:
All sub-tasks must have one of the following statuses to allow parent issue transitions: DONE 

If however there is still one or more sub-tasks OPEN (not closed) when transitioning the parent issue, only Transition 2 should be available. 

Some pseudo code to illustrate what I would like to do: 

if (all sub-tasks has status = closed){
    show.transition.name = "transition 1"
}
else (one or more sub-tasks has status != closed){
    show.transition.name = "transition 2"
}

Is it possible to add some kind of scriptrunner condition (jira expression) for this? Or is there any other solution suitable for my need.

Thanks.

Hey @Jesper Fransson and welcome to the community,

Normally on Cloud you should just be able to create a condition on the transition itself.

By setting a condition, the transition will not be shown unless the condition is fulfilled. Going by what you have as a requirement I would suggest using a "Sub-Task Blocking" Condition

 

This allows you to select the statusses the subtasks need to be in before the transition becomes available.
