It's a hidden algorithm that controls what happens when I write comments on my submissions at File Exchange. I failed to find a description of the behavoir and I'm frustraded.
4 Mar 2021: I intended to write two comments, two to keep issues separated.
- I wrote the first comment and clicked [Save]. The comment turned up in the top of the list of comments up and in in my Activity Feed. So far so good.
- I wrote a second comment. I didn't notice any sign that I was editing the first comment. I clicked [Save]. The second comment appeared at the top of the list of comments. I can't remember whether the first comment was still there.
- A couple of hours later I noticed that the first comment was missing.
- I recontructed the first comment in an editor. I copy&pasted from Activity Feed and some source code.
- I copy&pasted the recontructed first comment into the [Comments and Ratings] box, which was empty, and clicked [Save]. The second comment was overwritten.
4 Feb 2021: I intended to add text to a comment. I better be short because my memory may fail.
- I wrote and [Saved] a comment.
- I believe that the text of the comment appeared in the [Comments and Ratings] box when I selected the box.
- Three hours later [Activity Feed] I wrote some text at the end of the comment and [Saved].
- Result: two comments, the first without the added text and a second with the added text.
What am I doing wrong? How is it supposed to work?
5 Mar 2021a: I intended to [Save] the second comment of 4 Mar 2021
- Refreshed the m2uml page (to be sure)
- I copy&pasted the text of the second comment to the empty [Comment]-box and [Save]
- Refreshed the m2uml page. The second comment was added without affecting the first comment - as expected by Stephen.
I switched to Microsoft Edge. So far I had usef Firefox.
5 Mar 2021b: I intended to test editing.
- I wrote the letter "a" in the [Comment]-box and [Save]. The new comment appeared in the top of the list.
- I "clicked the cursor" in the [Comment]-box. The box remained empty.
- I wrote the letter "b" in the box and [Save]. The new "b"-comment replaced the "a"-comment in the top of the list.
- I closed the m2uml-page. Now the "b"-comment is permanently(?) in the list.
Conclusion: I failed to edit the "a"-comment.
