i expecting some like this :
everytime in IPrivatexxxView
import com.sap.tc.webdynpro.progmodel.api.*;
import com.sap.tc.webdynpro.progmodel.gci.*;
import com.sap.tc.webdynpro.progmodel.context.*;
import com.sap.tc.webdynpro.services.exceptions.WDRuntimeException;
when i search in help cannot find this above api....
pls help
