I am creating a mutable issue 'newSubTask' in my groovy script and also setting it's properties, and this is a subtask of the issue on whose On Create transition I am writing this post function. I was using ScriptRunner 4.3.13 up until now, and recently used the SR version 3.0.16 with another JIRA instance and copied this project and ran it and rceived this error of Propertyu not found. Is it due to the older version of script runner? Or is it because I might have made an error in copying? I think it is the former, though. How do I eliminate this error? (Since this JIRA instance has a lot of other projects which are using SR older version, I wouldn't want to upgrade SR and cause a havoc).
