Idea Summary
Oracle APEX should have an out of box Region/component called Attachment which will display all the attachments for a given ENTITY_NAME AND ENTITY_ID . Also it should have upload/view/delete atatchment option.
Use Case
Like in oracle EBS or fusion, we have plug the attachment region on any page and we just need to provide ENTITY_NAME , ENTITY_ID, INSERT ALLOWED, UPDATE ALLOWED AND DELETE ALLOWED option.
Preferred Solution (Optional)
Create New plugin called Attachment which will insert/update/delete attachments in an APEX_ATTACHMENTS table
