A fix for this issue is available in Confluence Data Center 9.0.1.
Upgrade now or check out the Release Notes to see what other issues are resolved.

We've been unable to reproduce since implementing fixes for https://jira.atlassian.com/browse/CONFSERVER-74533, so understand it to be resolved.

We are also affected by this bug in the version 7.13.2
It's very horrible to that this bug is known Atlassian since 2013.
I agree with Christoph Scharf, this lowers the trust of our users on the confluence tool. 

Please fix this issue, this lowers the trust of our users on the confluence tool. 

+1 Huge impact that requires repeat work and wasted time investigating where the checks disappeared to.

I have counseled users to patiently wait for a page to load before clicking "edit."  On some occasions, I saw the checks disappear when I try to edit a page too quickly upon visiting it. 

+1 This issue impacts the work of our project groups. They cannot trust this marco to manage and track certain task, so they have to double check. This renders it unreliable/useless/confusing.

Same here. Severity minor is far too low for us. Since it makes the tasks feature absolutely unreliable.

+1 This is painful for us.  It causes confusion for users who are incorrectly signaled that previously-completed tasks are suddenly somehow incomplete.  The issue renders the tasks feature unusable on pages that have frequent edits, which are most of our pages.

+1 We are experiencing this issue on 7.13. Because it makes users distrustful of the state of tasks in Confluence, this is a significant issue. 

+1 from our side, and still present on 7.4.10

The purpose of a task macro is to reliably manage tasks. It this basic functionality is hindered by "voodoo like task changing behaviour", the main purpose of the task macro will become needless. Thanks a lot for your understanding!

@pieter same here

This issue can also be easily reproduced when confluence collaborative editing is enabled:

1. Create and save a page with some task check-boxes.
2. Start Collaboratively editing the page (ask a colleague to help, or open an edit session in two browser tabs), and close the page without making any changes.
3. Check some of the tasks in view mode.
4. Start editing the page again, and save the page without making any changes.
5. Voila! All tasks are reverted to the state they had in step 2.

Hi osanico, mtran and kyabut,

This is a really painful bug affecting many teams and users. Is there any way to raise the priority?

Thanks,
Pieter

Please raise the priority of this issue! This is a MAJOR blocker for companies that need ISO compliance for their processes. It also makes Confluence tasks lists extremely unpredictable and unreliable, causing frequent communication issues in many teams at my company.

Please raise the priority on this issue! We experience this bug regularly and it makes task lists utterly useless. Running on Server 7.11.1, has been long present in previous LTS versions as well.

This bug has a big impact on our users work. Please elevate the priority. Thank you.

A user just reported this to me. We're on Server 7.5.1.

Additionally, users who have tasks marked unmarked after they had previously marked the task completed experience the following:

1. They received an email notification (if turned on ) stating that their task was marked incomplete with a link to the confluence page
2. If they used the link in the email from #1 to open up the confluence page, they received a warning message stating 'You are viewing an old version of this page. View the current version.'

We are using version 7.4.6.

Can the priority of this be raised? This is a pretty big data integrity issue that results in users  being unable to trust the accuracy of the Confluence product. Additionally, this has a financial impact on companies as well: No doubt I have duplicated testing steps when something becomes unchecked. It's really hard to keep track of exactly what I have/have not tested, which is why I use a checkbox to help me track. This issue occurs multiple times per week for myself, and others at my company have reported similar struggles.

We just recently starting experiencing this problem as well, has now been reported twice in less than a month. 

Data Center Version 7.4.0

Also frequently experiencing problems with this!

@Nick Sievert, reload the page has no effect here ...

In my instance, editing is not necessary - simply reloading the page will cause the checkbox to become unchecked. 

Version 7.4.1 is also affected

We have the same problem since we switched to Confluence 4 months ago. We work with large projects with dozens of tasks each. Not a day goes by when tasks that have long been completed are open again. There are 5 colleagues working in the team and everyone reports this problem daily.
I am shocked that this problem has apparently been known for years and nothing is done. You have to spend time every day researching whether an open task is actually open. For a product of this price range, I would have expected a quick and competent solution.

I've had this issue reported by multiple users. Please elevate priority. Thank you. 

Hi. We are also affected by this issue. Please check if you could elevate the priority of this bug.

One of our users just reported this, and I was surprised to discover that this bug has been known for almost 8 years. Please elevate the priority.

Thank you Atlassian!

I am surprised that the priority is low. We have already received numerous complaints from users.

One of our customers is affected by this bug as well. They are on Confluence 7.3.3.

As there has been another comment just a few days ago, it seems that this problem was re-introduced in 7.3.3?!

This issue also reproduced with below steps

Steps to Reproduce

1. Create Task List ([ ])
   • a
   • b
   • c
2. User A check a, b, c and save as draft in edit page
3. User B check and uncheck a, b, c in view page
4. User A Open edit

Expected Results

a, b, c are still checked in User A's draft

Actual Results

check marks are cleared

Would it be possible to raise the priority of this bug?

This has a major impact on people who use Confluence tasks to track their work and the work of their team. If Confluence is losing information, it means that Confluence tasks lists are unreliable and therefore people might think of Confluence as unreliable.
