I just wanted to share a simple workaround for the missing support of the "Append Changes to Existing Text" option for Multiline text fields in Nintex Forms for Office 365.
Apparently on 26th September Nintex announced that this feature is planned for development, but I can't wait that long... Support lists with versioning turned on and where "Append Changes to Existing Text" is set to "Yes."...
For my solution I was using the new responsive forms but it should work also in the classic ones.
What you need
• Every comment field can be only edited by the user that made the comment otherwise it will be disabled.
• Unlike in SharePoint you can see old comments while editing.
• People can be destructive and delete each others comments.
• You don't get a time stamp like in SharePoint.
You must be a registered user to add a comment. If you've already registered, sign in. Otherwise, register and sign in.
