Passing Data Between Views

Hi

I am passing data with below, but I don't know if it is
good design for this. How is the right?

... first view

void CMainView::makeList( const TDesC8& aXML )
   {
   AppUi()->ActivateLocalViewL(  
                  TUid::Uid(EMultiViewsRequestFilesId),
                  TUid::Uid(EMultiViewsRequestFilesId), aXML);
   }

... second view

void CRequestFilesView ::DoActivateL(
                                   const TVwsViewId& aPrevViewId,
                                   TUid aCustomMessageId,
                                   const TDesC8& aCustomMessage)
   {
   iContainer = new (ELeave) CRequestFilesContainer;
   iContainer->SetMopParent(this);
   iContainer->ConstructL(ClientRect(), aCustomMessage);
   AppUi()->AddToStackL(*this, iContainer);
   }
