checked task completions get unchecked by itself

[Jürgen Buchinger]

Hi Confluencers

Sometimes, users report to me that completed ticks of tasks have disappeared after page updates, allegedly without actively clicking on them.
The mail notification then reports "xy has marked a task as incomplete".
After enquiring with user xy, he swears that he did not make the change, but only edited the line actually intended for him.
However, the comparisons in the version history show that user xy has removed the tick.

An Atlassian article describes such behaviour in version 6.14.

Our version is 7.4.6.

I checked the page HTML markups and found no duplicate task IDs.
But I can't imagine that several users are so confused that they keep clicking on the wrong tasks.

Many thanks for your answers!
Regards, Jürgen

I have had this happen in the past where one user has the page open and is editing it when another user just clicks the check mark on the page to mark it complete.  Then when the user saves the page with it unchecked it overwrites the check mark.  Could this be happening?

[Jürgen Buchinger]

Thank you for this hint. That is possible. I will check this if the case occurs again.

I have tried to reproduce the behaviour again. I did not succeed in reproducing the error in version 7.4.8. It is possible that the affected pages were created in an older version.

@Jürgen Buchinger I am not sure if an older version page would be the culprit or not. It is odd that it has not occurred again and that you can not recreate it.
