Usually the system is not committing such objects to the database. Are you sure that it ends up in DB?
Is your object a specialization of System.FileDocument or System.Image? The file uploader sometimes behaves like this.
As mentioned before, your entity is a specialization of System.Image. The image uploader always commits on each button click when a file was selected. The only thing that you can do is building a proper delete behavior and a cleanup action that searches for orphaned objects from time to time.
Mendix does not committ objects to the database.
