how to fix errors after push-in refactor

[golfp-96]

STS 2.9, Roo 1.2

I made push-in refactor to move update method into java class.
Final code is as follows:

@RequestMapping("/notebooks")
@Controller
@RooWebScaffold(path = "notebooks", formBackingObject = Notebook.class)
public class NotebookController {
	@Autowired 
	private NoteService noteService;
	
	@RequestMapping(method = RequestMethod.PUT, produces = "text/html")
    public String update(@Valid Notebook notebook, BindingResult bindingResult, Model uiModel, HttpServletRequest httpServletRequest) {
        if (bindingResult.hasErrors()) {
            populateEditForm(uiModel, notebook);
            return "notebooks/update";
        }
        uiModel.asMap().clear();
        notebookService.updateNotebook(notebook);
        noteService.updateNotesWithNoteBook(notebook);
        return "redirect:/notebooks/" + encodeUrlPathSegment(notebook.getId().toString(), httpServletRequest);
    }
}

noteService is in NoteServiceImpl, but there is also error (second line from bottom)
Also STS complaints it can not find populateEditForm and so on (strings in red).. How to fix it?
