Issue Summary
We have observed Null Pointer Exception in the logs after checking and unchecking an inline task on a Confluence page
Steps to Reproduce
- Start a new confluence instance
- Create a new page
- Add a task, check it, assign it to a user (e.g. @admin)
- Publish the new page
- On the resulting page view: uncheck the new task again
Expected Results
Confluence processes the unchecking without error.
Actual Results
Tasks checking and unchecking is not properly processed and tasks appear to be checked and unchecked at random, without any user input.
The below Null pointer exception is thrown in the Atlassian-confluence.log file:

Upgrade now or check out the Release Notes to see what other issues are resolved.
Please provide a fix for LTS, this is major issue that affects a lot of people !!!
Is it planned to fix it in version 7.13, the latest LTS available?
A fix for this issue is available to Server and Data Center customers in Confluence 7.15 Upgrade now or check out the Release Notes to see what other issues are resolved.
From our point of view, a backport to the LTS version 7.13. (which is used by most major customers) would be the least you could expect as a customer.
thanks & regards, Marco
@Quan, we still experience this issue while we are on Confluence Cloud.
According to this support page (https://confluence.atlassian.com/confkb/how-do-i-know-what-version-of-confluence-is-running-179441565.html) we should be on the 'latest' version.
How do we know which version we use on Confluence Cloud and if this problem is fixed for us as well?
