Script to transition a subtask when another subtask is resolved.

[Batu Sanchez]

Let me explain my current situation.

I have 2 workflows defined for a Kanban Project:

• The first one has 4 statuses (TODO, INPROGRESS, REVIEW & DEFINED), this is the main workflow for Developers to work with. When the Developer creates a Task in this project, I set up the transition so it creates 5 different sub tasks (A, B, C, D & Report), 4 of which (A, B, C, & D) follow this WF. B can't be resolved until A is, C can't be resolved until B is and so on.
• And I have another workflow defined with 5 statuses (OPEN, A COMPLETED, B COMPLETED, C COMPLETED & D COMPLETED) for the last subtask (Report). The intention of this subtask is to report the status of the other 4 subtasks.

My question is.

How can I define a Post Function Custom Script to automatically transition the Report Subtask when the other subtasks are resolved?

Do I need to create a link between the subtasks when they are created?

I made a research in the community and didn't found a something like this

Please make it as simple (for dummies) as possible.

So I got no answers but I found a solution if anybodyelse requires it:

I added the following Custom Scripted PostFunction in the transition from "REVIEW" to "DEFINED":

/**
*The script transitions the subtask "Report" when the subtask "A" transitions to Defined
*/

    MutableIssue parent = issue.getParentObject() as MutableIssue;

    Iterator<Issue> iterator = subTaskList.iterator();
    while(iterator.hasNext())
    {
        Issue subTaskObj = iterator.next();
        if (subTaskObj.getIssueType().getId() == "59" || subTaskObj.getStatus().getId() == "26")//59 is the ID for "Report" subtask issue type & 26 is the ID for the status "Open"
         {
            workflowTransitionUtil.setIssue((MutableIssue) subTaskObj)
            workflowTransitionUtil.setUserkey(currentuser)
            workflowTransitionUtil.setAction(21)//21 is the transition ID from "Open" to "A - Defined"
            workflowTransitionUtil.validate()
            workflowTransitionUtil.progress() 
         }
