Not able to copy file content to another entity

Hi Currently I am working on mendix project and while trying to copy file from one entity to another, the former entity not showing the inherited file attributes to set. For eg I have Event (Specialization FileDocument) and Fileupload (Specialization FileDocument) entity and in microflow I want to set content of File associated with Events to  file associated with Fileupload, but when trying to set attribute for Fileupload, the attributes of FileDocument doesnt appear.   So my question is – how I can copy the content of file (FileDocument) from one entity to another ?

Use the DuplicateFileDocument Java action from CommunityCommons.
