Idea Summary
Enable File Browse items in Oracle APEX to store uploaded files directly at the session level without requiring a page submission. This would allow developers to access uploaded file data immediately through AJAX or client-side logic, enhancing interactivity and eliminating the dependency on temporary tables or page reloads.

Use Case

• Display uploaded file previews instantly (images, PDFs, etc.) without submitting the page.
• Validate or transform files asynchronously before final submission
• Instantly use uploaded files as inputs for AI or automation processes triggered via AJAX.

Preferred Solution (Optional)
Introduce a native APEX feature or Dynamic Action option that automatically sets the File Browse item value in session state upon file selection (change event). The uploaded file would then be accessible via session APIs (e.g., apex_util.get_blob_file) without requiring a page submit.
