Answer overwritten when multiple users edit the same question

[AliceWi]

Description / Beschreibung

If two users answer a question simultaneously and then click "Proceed," only the response of the user who clicked "Proceed" first will be saved.

Expected behaviour / Erwartetes Verhalten

Based on the issue #626 and the release notes of 2.1.0, I expect the following:

Conflicts will be prevented when users attempt to edit the same values simultaneously.

Steps to reproduce / Schritte zum Reproduzieren

1. User 1 edits Question A in RDMO.
2. User 2 edits Question A in RDMO.
3. User 1 clicks "Proceed".
4. User 2 clicks "Proceed" after User 1.
5. Result: Question A contains the answer from User 1.

Context / Kontext

RDMO Version 2.1.3

Hi @AliceWi! In your example, does User2 get a message that the value is not saved? If yes, that is (at least my) expected bahavior. If not, this might be a bug which is already fixed, but only in the upcoming release.

Hi @jochenklar! I double-checked and noticed that the two "Proceed" Buttons (under the questions and on the right side under the progress bar) have different behaviours: The Proceed Button under the questions works as expected. However, the Proceed Button under the progress bar continues to the next page regardless of the warning. As a result, the user's changes are lost and the warning only appears for a split second, with that likely going unnoticed.

This is a bit odd, the proceed button on the right works a bit different as the blue one on the bottom, but both should save the input. Is the question kind of special?

Never mind, I found it. The error message is shown, but then the page is changed anyway. The same is probably the case if you use the navigation. I will look for a fix.
