Block subtask creation when the parent issue is done for specific issue type

[Ryan Bullock]

We have a workflow with the issue types Epic, Task, and Sub-task. We also have a separate workflow with the issue type Request. The script is blocking the Sub-task creation as expected, but is also blocking the ability to create Epic and Tasks that follow the same workflow. Ideally we would like Sub-tasks to be blocked if the Request issue type is Closed/Done, but it is fine if it applies to all. Any ideas?

Have tried multiple variations of the solutions offered here but none have worked:

Hi @Ryan Bullock

For your requirement, I suggest using ScriptRunner's Custom Script Validator instead of the Simple Script Validator.

Below is a sample working code for your reference:-

import com.opensymphony.workflow.InvalidInputException

if (issue.isSubTask() && issue.parentObject.status.name == 'Done') {
 throw new InvalidInputException('sub-tasks', 'Sub-Taks cannot be created if the issue is Done')
}

Please note that the sample code above is not 100% exact to your environment. Hence, you will need to make the required modifications.

Below are the screenshots for the validator configuration:-

 1. Select the Create transition. Once the dialog appears, click on the Validators link as shown in the screenshot below:-

2. Once on the validators Post-Function configuration page, click add validator as shown in the screenshot below:-

3. Select Custom script validator [ScriptRunner] as shown in the screenshot below

4. Finally, add the sample script I provided into the Inline editor and publish the changes.

Below are a couple of test screenshots for your reference:-

1. To test the validator, I am going to try and create a Sub-task on a Story that is part of an Epic which is in Done status as shown in the screenshot below:-

2. I enter some values into the Sub-task fields and click on the create button as shown in the screenshot below:-

3. As expected, the error message does not permit me to create Sub-tasks for Done Issues.

4. Next, I try to create a new Story and enter some details as shown in the screenshot below:-

5. As expected, the new Story is created without any issues.

I hope this helps to solve your question. :-)

Thank you and Kind regards,

Ram

Hi Ram, thank you for the detailed solution! It is working as expected as it no longer blocks the Epic and Tasks.

Is there a way to apply this so that it only applies to a specific parent issue type? For example, if we wanted to have it only apply to subtasks created under a 'Done' Task issue type, but not apply if it is a Subtask under an Epic? 

Cheers,

Ryan

Hi @Ryan Bullock 

If you intend to make the validator specific for only the Task issue type, all you have to do is modify the if condition from this:-

import com.opensymphony.workflow.InvalidInputException

if (issue.isSubTask() && issue.parentObject.status.name == 'Done') {
 throw new InvalidInputException('sub-tasks', 'Sub-Taks cannot be created if the issue is Done')
}

to this:-

import com.opensymphony.workflow.InvalidInputException

if (issue.isSubTask() && issue.parentObject.status.name == 'Done' && issue.parentObject.issueType.name == 'Task') {
 throw new InvalidInputException('sub-tasks', 'Sub-Taks cannot be created if the issue is Done')
}

I hope this helps to solve your question. :-)

Thank you and Kind regards,

Ram
