Hi,

i do the exercise 3 from Ja312 and in the Book i have to Add

this code Below:

the problem is that i have redlines in getCmp_firstname

and in wd.Context how can i solve it?

Regards

For resolving the issue of getCmp_firstname , i go to the component controller "Exc_IntroController" and select the context tab. There in the left Window i have context ->firstname ->lastname

public void onPlugFromStartView(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
  {
    //@@begin onPlugFromStartView(ServerEvent)
    
    String firstname =
    wdThis.wdGetExc_IntroController().wdGetContext().   
	currentContextElement().getCmp_firstname(); 
    
    
    String lastname =
	wdThis.wdGetExc_IntroController().wdGetContext().
	currentContextElement().getCmp_lastname();
		
		if ( ( firstname!=null ) & (lastname!=null)){
			response = "hellow , "+firstname+" " +lastname ;				
		}else {
			response = "Hellow, stranger";
		}
		
		wd.Context.currentContextElemnt().set_txtviewresult(response);
    
    
    //@@end
  }
