I have simple parallel review workflow where author creates a review with one or more reviewers to review a document. Currently, the workflow has reviewer task outcome as either accept or reject. Now, a new requirement is to update the comments but not take any action(accept/reject), when a reviewer updates the comment, author needs to be notified via email but the reviewer should still needs to have the task assigned to him.
Basically, is there a way for a user task to perform actions without state change?
