    Default Paging grid with RequestFactory and related entity - doesn't load related entity

    Paging grid with RequestFactory and related entity - doesn't load related entity


    Hi all,

    i have a problem with paging request factory grid.
    If I try to fetch entities that have related entities(lazily loaded) through request factory,and show results on paging grid, i run into a problem.
    The implementation is similar to this:
    http://www.sencha.com/examples/#Exam...estfactorygrid
    I have included the "with("partner") statment on request context,but according to backing database logs, partners(related entity) were never loaded from database.If I leave the PropertyAccess as is, and only replace paging loaders and proxies with straightforwart call to fire() the request to server, I get everything working as expected.
    "partner" entities are loaded as expected.
    Is there anything that I missed?
    part of the application code:



    Entity proxy:
    Code:
    @ProxyFor(value=Kupac.class, locator=EntityLocator.class)
public interface KupacProxy extends EntityProxy {

    Long getVersion();
    
    Integer getId() ;
    void setId(Integer id);
    
    //nested entity
PartnerProxy getPartner();
    void setPartner(PartnerProxy partner);
    
    String getOib();
    void setOib(String oib);
    
    String getImePrezime();
    void setImePrezime(String imePrezime);
    
    String getAdresa();
    void setAdresa(String adresa);
    
    String getMjesto();
    void setMjesto(String mjesto);
    
    Boolean getAktivan();
    void setAktivan(Boolean aktivan);
    
    String getDefaultBrojKartice();
    void setDefaultBrojKartice(String defaultBrojKartice);
    
    Date getDatumOtvaranja();
    void setDatumOtvaranja(Date datumOtvaranja);
    
    //Set<KarticaProxy> getKarticas();
    //void setKarticas(Set<KarticaProxy> karticas);
    
}
Code:
    Code:
        public interface KupacProxyProperties extends PropertyAccess<KupacProxy>{
        ModelKeyProvider<KupacProxy> id();
        ValueProvider<KupacProxy, String> oib();
        ValueProvider<KupacProxy, String> imePrezime();
        ValueProvider<KupacProxy, String> adresa();
        ValueProvider<KupacProxy, String> mjesto();
//this property fails,it doesn't load related entity "partner"
@Path("partner.naziv")
ValueProvider<KupacProxy, String> partner();
        ValueProvider<KupacProxy, Boolean> aktivan();
        ValueProvider<KupacProxy, String> defaultBrojKartice();
        ValueProvider<KupacProxy, Date> datumOtvaranja();
    }
    Code:
    ctx = Kvitto_Card_Manager.KvittoRF.KupacRequest();
        RequestFactoryProxy<FilterPagingLoadConfig, PagingLoadResult<KupacProxy>> proxy=new RequestFactoryProxy<FilterPagingLoadConfig, PagingLoadResult<KupacProxy>>() {
            @Override
            public void load(FilterPagingLoadConfig loadConfig, Receiver<? super PagingLoadResult<KupacProxy>> receiver) {
                List<SortInfo> sortInfo = createRequestSortInfo(ctx, loadConfig.getSortInfo());
                List<FilterConfig> filterConfig = createRequestFilterConfig(ctx, loadConfig.getFilters());

//notice the "with" parameter is included
                ((KupacRequest)ctx).getKupci(loadConfig.getOffset(), loadConfig.getLimit(), sortInfo, filterConfig).with("partner").to(receiver);
                
                ctx.fire();
            }
        };

        
        Kupacloader = new PagingLoader<FilterPagingLoadConfig, PagingLoadResult<KupacProxy>>(proxy) 
        {
            @Override
            protected FilterPagingLoadConfig newLoadConfig() {
                return new FilterPagingLoadConfigBean();}
            };
