Hi
Thanks for your request. Unfortunately this issue is unresolved yet. We will try to resolve this issue in our next release. But currently I can’t provide you exact date when this issue will be fixed. Thanks for your patience.
Best regards.
This is fixed in the next release that is coming out, but you can workaround now. Just set Comment.Author and Comment.Initial properties to non null values. Easy.
