- Create a screen for creating sub-tasks that includes a required field
- Ensure that the project has multiple sub-task types that all use that screen for creating an issue
- Start creating a new sub-task in the parent issue and select a sub-task type other than the default.
- click create, the create sub-task screen should be shown
The Selected sub-task type from the parent issue would be carried over to the create issue screen.
The selected sub-task type is re-set to whatever the default is in the create issue screen and is not carried over.
Currently there is no workaround. If you encounter this issue, don't bother setting the type for projects that you know are impacted. Alternatively you can change the required fields to no longer be required or remove the required fields from the create issue screen for the sub-tasks to prevent the create sub-task screen from blocking the sub task creation.
