WD4A application FPM framework - Explicit Configuration

Hi All,

Have been following FPM for ABAP - Developer's guide, to develop a test WD4A application with FPM framework. After creating the Webdynpro Component and Application while trying to change the Component Configuration, the tab 'Explicit Configuration' at any time is not active its simply grayed out.

Could you please help me in finding the reason?
