I'm attempting to show the last internal comment on a customer scripted field using Script Runner. I'm using the following script which returns the last comment, however it does not filter out external comments added via the portal. Is there a way to exclude external comments?
import com.atlassian.jira.ComponentManager
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.comments.Comment
import com.atlassian.jira.issue.comments.CommentManager
import com.atlassian.jira.component.ComponentAccessor
def commentManager = ComponentAccessor.getCommentManager()
def comment = commentManager.getLastComment (issue)
comment.body + " Author: " + comment.authorFullName
