Issue

When developing a Mendix offline-first application, entities are configured to use the Never synchronization mode. According to the Mendix documentation, the Never synchronization mode does not support FileDocument or ImageDocument entities, or their associated entities. However, during end-to-end testing, files and images are successfully stored locally, and the application logic handles these documents without errors in Never synchronization mode.

Environment

Native Mobile

Cause

Changes were made to improve local synchronization. As a result of these changes, file and image handling in the Never synchronization mode functions in end-to-end testing, despite the documented limitation for FileDocument and ImageDocument entities.

Solution / Workaround

If files and images function correctly in an application configured with the Never synchronization mode, continue using the current implementation.
