Opening Multiple Project Overview at once can lead to Incorrect Rendering of Content

Summary

Users loading multiple project overview pages at a time will render incorrectly to some of its content, following the last page loaded by the user. This can easily reproduced when loading the Project Overview page took 5 seconds or more.

Environment

• Tested on JIRA 6.4.12

Steps to Reproduce

1. Disable new Project Sidebar
2. Open 4 projects in different tabs, land at Project Overview page
3. Ensure all projects took more than 5 seconds to load
4. Refresh all tabs quickly

Expected Results

The content in each Project overview renders correctly

Actual Results

3 out of 4 projects has incorrect content which retrieved from the last refreshed project.

Notes

• Jira page is builded from many small web fragments. Each web fragment has template that defines how it will look like. The template use values like user-name, project-key from provided context.
• This is interesting how legacy project page populate the project object to the context. When user visit project page, it save the last visited project into user history. Later when page is rendered, for each web fragment, everytime it take the latest project from user history.
  If in meantime user will open another project page, the history will be changed and semi rendered pages will start rendering web-fragments for a different project.

Workaround

• Use new Project Sidebar or Project Centric view
