Can different sub-tasks listen to eachother?

[Johan Söderström]

I´m gonna try to simplify this by making a scenario:

I have three different issue types: Story, sub-task and test-task.

Story workflow is: To Do - In Progress - Test - Done

Sub task and test task have both different sub-workflows

1. When all sub-tasks are done I want the Story to transfer to In progress (this is no problem).
2. When all sub-tasks and test-tasks are done I want the Story to transfer to Test (this is a problem). 
3. If the test-task is Done before the sub-task nothing should happen to the story until the sub-task also is done(this is a problem).

As i understand it number 2 and 3 is not possible because there are no post-functions between the childs. Am I correct?

Correct.  You'd need some code in the post-functions on the two sub-task workflows that could check the other sub-tasks on the parent for your business logic.

Thank´s Nic for your quick response. Could you please explain me or give an example how to do that?

[Nic Brough -Adaptavist-]

I'm afraid that's where I have to let you down - you can't add such code to Cloud systems.

Thanks again for your answer.
