Hi
my problem not solved, ones check it. in ABAP sys date is 2008.01.01 but our wdAppl doesnot accepts this format so i have taken like 01/01/2008
component controller init()
=====================
Zvendor1_Input input = new Zvendor1_Input();
        wdContext.nodeZvendor1_Input().bind(input);
     Date d = new Date(Calendar.getInstance().getTimeInMillis());
        wdContext.currentZvendor1_InputElement().setVendor("");
        wdContext.currentZvendor1_InputElement().setCo_Code("");
        wdContext.currentZvendor1_InputElement().setPosting_Date_From(d);
        wdContext.currentZvendor1_InputElement().setPosting_Date_To(d);
action button()
=================
try {
          wdContext.currentZvendor1_InputElement().modelObject().execute();
          wdContext.nodeOutput().invalidate();
     } catch (WDDynamicRFCExecuteException e) {
          e.printStackTrace();
     int i = wdContext.nodeItab().size();
     if(i==0)
          wdComponentAPI.getMessageManager().reportException("records not found",true);
     wdContext.currentZvendor1_InputElement().modelObject().modelInstance().disconnectIfAlive();
if i can print any msg it can show but it does not show fields(i/p,o/p) and search button  without details
it doesn't show any errors
when i take the i/p of date formates problem raises  otherwise it shows(fetches) correct data
