I am trying to develop a Web Dynpro component to enable a user to select a local directory on their client to which they can then download a pre-named file from the app server. All I need the UI to do is allow the user to select a target folder (not a file) on the client PC. The functionality that I am looking for is similar to that provided by cl_gui_frontend_services=>directory_browse method (which will not run from within a Web Dynpro component).
The File Upload Web Dynpro element is the only element which looks as though it might do what I want. However it only appears to support file selection (not folder selection). Documentation for CL_WD_FILE_UPLOAD also appears to be unavailable in English.
Thanks in advance.
