Dump in Webdynpro abap. CL_GUI_FRONTEND_SERVICES

Question

Hi ,
my requirement is to copy the clip board data and bring that to internal table.
i have created the Function module for that inside that i have used CL_GUI_FRONTEND_SERVICES=>CLIPBOARD_IMPORT method.
My function module is working fine when i executed in se37. i used the same FM in a Se38 program and its working fine there also.
but when i used the same in webdynpro component it is giving dump.
Can any one help me !!!
Thanks

Hi dinesh ,
WDA does't have clipboad Functions & you cannot use the  CL_GUI_FRONTEND_SERVICES because of the below reason
The class CL_GUI_FRONTEND_SERVICES supports the SAP GUI for Windows, the SAP GUI for the Java Environment and the SAP GUI for HTML. WebDynpro applications are not supported.
you can refer Thomas answer in below link .
[upload from clipboard option in webdynpro abap selection screen|upload from clipboard option in webdynpro abap selection screen]
alternatively you can achive using ABAP memory
creat a button for COPY ..inside that Export the value to the memory ID
and create a button for paste and import the value using the memory ID
