Property Calculator - Comments captured through the workflow

Is this for separate assignment or just assigning the object?  

This is for just assigning the object

I can setup the below to capture whenever there is a new comment. However I'm at a loss how I'd add the users name into the expression next to the comment.

Then after getting the name, I'd love a timestamp in the correct regional format

Basically building out the comment toggle on the metadata card, and doing it in a multiline text. Doing this for a couple of reason, the first being a user that gains permissions at say version 7 of the object, will not see any comments prior. The second is for an internal process to send a notification as part of the workflow will all the comments.

Hi!

I had a similar requirement (see Is there any way to show comments from PREVIOUS STATES in a workflow notification? - General Topics - Forums - M-Files Community), and the solution was to create a Property Definition (text) that catches each comment ('Calculate Expresssion') and then these properties can then be included in notifications.
I guess in your case, if you want to capture the comments from each state - you would need to create multiple properties using each workflow state as a condition. Then these properties can be summarised in the notifications.
Maybe a screenshot from our Property Calculator module demonstrates how we did this:

Thanks Patrick, a very similar scenario.

By using the condition type 'changed property value' and then adding a secondary condition of comment not being empty, I am able to write all comments into a multi text property without issue.

I setup a property transition timestamp, and within the workflow used set the property to update the transition time. Then using property calculator I used the convert date function to changed the transition date to text. The reason for this is because if I use the Timestamp property within expression, the format is the wrong region.

I'm confident I can get a multitext with only the comments and the time they occurred, the missing piece is getting the user name who completed the transition.
