My requirement is to display the powl selected data to the detailed with in the same window. Everything is working uptill displaying powl , I developed component controller context and view context, set up plugs at the view and at the window. At the defaultevent handling method I called the out plug to call the master powl, and that is working, but next when i call the wd_comp_controller->set_data( podata). and call then call the detail plug, nothing comes up to show in the detail view and the page coming out blank.  I am having problems in calling the detail_view, i have already setup the update_Detail_data method of the and calling the I_powl_data importing parameter. I am using feeder CL_MM_POWL_VENDOR_LIST for the powl list display.  My main question is , how i can call the detail_view or what i needs to do so that i can write code in the default even handling method of the main_window?
