Problem

Administrators are unable to modify permissions for the Storage Format Source Editor. When attempting to enable the editor for all users or a specific subset, the UI appears to process the request (returning a 302 redirect), but the changes do not persist after the page reloads. The tickboxes and group settings revert to their previous state.

Environment

• Confluence Data Center 8.9.8
• Storage Format Source Editor for Confluence version 2.1.0 and earlier

Steps to Reproduce

1. Navigate to Confluence Administration Administration > Source Editor
2. Attempt to enable the Source Editor for all users or add a specific group to the allowed subset
3. Click Save

Expected Results

The configuration changes should be saved to the database/BANDANA and persist across page refreshes.

Actual Results

• The settings do not save
• The network trace shows a POST to /admin/sourceeditor/updateconfiguration.action returning a 302
• Followed by a GET to /admin/sourceeditor/viewconfiguration.action returning 200

but the UI shows the original (disabled) state. There are no related logging entries in the application logs.

Workaround

Upgrade to Confluence 9.2.x or 10.2.x, which is unaffected by this behaviour
