Hi Ricardo,

For resolving the issue, please go to the component controller "Exc_IntroController" and select the context tab. There you will find the attribute under Context. There should be n attribute with name exactly as 'Cmp_firstname'. If the name is not exactly same then replace the below line of code with the exact name:

String firstname =

wdThis.wdGetExc_IntroController().wdGetContext().

currentContextElement().get_Cmp_firstname_();

Hope this resolves your issue.

If variable response is not declared somewhere else, put String response=null; at the begining of the method.

public void onPlugFromStartView(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
  {
    //@@begin onPlugFromStartView(ServerEvent)
    String response = null;
