Copy sub-task comment to parent

[Steve Van Der Weide]

After a sub-task is transitioned from OPEN to APPROVED, the user is prompted to add a comment. I have a post function that should grab that comment (I'm using getLastComment because I anticipate only one comment for now), and post a new comment with the same body text to that sub-task's parent.

Here's the script I'm using ... 

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue 
import com.atlassian.jira.issue.comments.CommentManager

Issue parentIssue = issue.getParentObject()

def feedback = ComponentAccessor.commentManager.getLastComment(issue)

if (feedback) {
	create(parentIssue, feedback.getAuthorApplicationUser(), feedback.getBody(), true)
}

... which gives me the following error:

2017-05-16 14:44:44,314 ERROR [workflow.ScriptWorkflowFunction]: *************************************************************************************
2017-05-16 14:44:44,314 ERROR [workflow.ScriptWorkflowFunction]: Script function failed on issue: ITCM-327, actionId: 11, file: <inline script>

Possible solutions: grep(), iterator()

Any ideas why this might be occurring? If I understand the error log correctly, one of the arguments I'm passing to create() is the wrong type, but I can't figure out which.

Thanks in advance.

I figured it out. I was supposed to be using: 

ComponentAccessor.getCommentManager().create( ... )

instead of just create( ... ).
