I am currently building a Web Dynpro application in which I need to display a File Save Dialog popup on the Netweaver Portal.
Now, I used the standard file_save_dialog method from the class CL_GUI_FRONTEND_SERVICES, but this gives me a dump on the Portal saying: Exception condition "NOT_SUPPORTED_BY_GUI" raised.
I believe that this is because the method file_save_dialog displays the popup in the backend but cannot render the functionality on the front-end portal.
Please advice if there is any suitable method / function module which does the same functionality and is compatible with the front-end.
Thanks in advance for your help....
