Summary

In a page containing multiple task items, when checking/unchecking one of the task items, some of the other task items replicate the behavior.

Environment

Confluence 6.14.3

Diagnosis

1. In a page that contains those Task Items, click on the top right menu: ...
2. Click on View Storage Format;

3. You will see, in the storage format, that some of the Task Items contain a duplicated value in the <ac:task-id> tag.

   Page Storage Format

   <ac:task>
   <ac:task-id>1</ac:task-id>
   <ac:task-status>complete</ac:task-status>
   <ac:task-body><span class="placeholder-inline-tasks">Text for task item macro 1</span></ac:task-body>
   </ac:task>
   <ac:task>
   <ac:task-id>2</ac:task-id>
   <ac:task-status>complete</ac:task-status>
   <ac:task-body><span class="placeholder-inline-tasks">Text for task item macro 2</span></ac:task-body>
   </ac:task>
   <ac:task>
   <ac:task-id>2</ac:task-id>
   <ac:task-status>complete</ac:task-status>
   <ac:task-body><span class="placeholder-inline-tasks">Text for task item macro 3</span></ac:task-body>
   </ac:task>

Cause

Each Task Item in the Task List macro must have a unique ID. When two or more Task Items have the same task-id value, checking one of them will trigger other tasks with the same id to check as well.

Solution

You need to eliminate the duplicated task-ids. There is two ways to accomplish this:

• Re-create the Task Item:
  1. Copy the Task Item description to another text editor;
  2. Delete the Task Item;
  3. Manually create a new Task Item by clicking on Insert more Content ( + ) > Task List. Do not copy another Task Item from the same page;
  4. Paste the description from the text editor into Confluence.
• Directly edit the page source code:
  1. Install the Confluence Source Editor app;
  2. Edit the page;
  3. Within the Page Editor, click on the Source Editor: < >;
  4. Manually replace the duplicated task-ids for unique values.
