JPA/Hibernate, Spring Roo: can Repository and ActiveRecord coexist?

I have the following Spring MVC controller that uses both a repository and an active record. I systematically get the following exception:

Code:

---

Note that the line does exists in database!!

Here is my controller code:

Code:

---

@RequestMapping("/plis")
@Controller
@RooWebScaffold(path = "plis", formBackingObject = Pli.class)
@RooWebFinder
public class PliController {

        @Autowired
        private PliRepository pliRepository;
       
        @RequestMapping(params = { "find=ByMultiField", "form" }, method = RequestMethod.GET)
    public String findPlisByMultiFieldForm(Model uiModel) {
                populateMultiFieldForm(uiModel);
        return "plis/findPlisByMultiField";
    }
   
    @RequestMapping(params = "find=ByMultiField", method = RequestMethod.GET)
    public String findPlisByMultiField(@RequestParam("identifiant") String identifiant, Model uiModel) {
        uiModel.addAttribute("plis", pliRepository.findPlisByMultiFieldQuery(identifiant, null, false, false, null, false, null, null).getResultList());//REPOSITORY USAGE
        return "plis/list";
    }
         
    void populateMultiFieldForm(Model uiModel) {
        uiModel.addAttribute("pli_datereception_date_format", DateTimeFormat.patternForStyle("M-", LocaleContextHolder.getLocale()));
        uiModel.addAttribute("conteneurnums", ConteneurNum.findAllConteneurNums());//ACTIVE RECORD USAGE
        uiModel.addAttribute("statutplis", Arrays.asList(StatutPli.values()));
    }
}
