pojo inside the pojo using bean item

Vaadin 6 / 7 / 8 Framework Data Binding
3

Thanks for the reply. I will go more specific on this.I am using vaadin 7.
basically what i have done…

CatCatalogue catalog=new CatCatalogue();

BeanItem bean=new BeanItem(catalog);

final Property property1=bean.getItemProperty(“name”);
final Property property2=bean.getItemProperty(“catCatalogueStatuses.statusId”);
final Property property4=bean.getItemProperty(“catCatalogueType.typeId”);

for status selection i have taken one combo-box with bean item container>>

final BeanItemContainer beans3 =
new BeanItemContainer(CatCatalogueStatuses.class);

for (CatCatalogueStatuses catalogueStatus :status.loadCatalogStatusFromWS()){

         beans3.addBean(catalogueStatus);
       		}
    
final ComboBox satsus=new ComboBox("",beans3);
 satsus.setImmediate(true);

satsus.setPropertyDataSource(property2);

satsus.setItemCaptionMode(AbstractSelect.ItemCaptionMode.ID);
satsus.setItemCaptionPropertyId("name");

and for type selection >>

final BeanItemContainer beans2 =
new BeanItemContainer(CatCatalogueType.class);

for (CatCatalogueType catalogue :type.loadCatalogTypeFromWS()){

  beans2.addItem(catalogue);
			
}
    
    
    
final ComboBox type=new ComboBox("",beans2);

type.setPropertyDataSource(property4);
   
 type.setItemCaptionMode(AbstractSelect.ItemCaptionMode.ID)
 type.setItemCaptionPropertyId("name")

for insertion i was calling hibernate function>>

        cat.save(catalog);

firstly it shows conversion exception that CatCatalogueWSStub.CatCatalogueStatuses is not the type of CatCatalogestatusesWSStub.CatCatalogueStatuses.

and it shows error of catCatalogueStatuses and catCatalogueType as null on console.

i think we have to write custom convert for this i tried it but, not works with combobox. please let me know is there any demo
code on this.

i tried lot on it but , unfortunately not works.
suggest any solution on this.

Thanks/
